GolfWRX exclusive: The story behind the new Costco KS1 putter



Costco, together with its Kirkland Signature brand, is one of the biggest forces in retail. Once again, it is disrupting the golf equipment space with the introduction of the company’s very first original golf club: the KS1 putter.

In an exclusive interview with GolfWRX, Tim Farmer, Costco vice president and general merchandise manager, dug into the details behind the putter. Farmer also spoke at great length about Costco’s other golf products, including the wildly popular Kirkland Signature four-piece golf ball and the current Kirkland three-piece urethane ball, which upon the time of publication has over 17,000 reviews and a 4.5/5 star rating.

The Costco Golf story

“The approach to creating the KS1 putter was no different than creating any other Kirkland Signature product – to work with a manufacturer to create something that offers exceptional value to our customers”

-Tim Farmer

First, some background on the Kirkland Signature brand, from Costco 

“By taking the lead in sourcing and formulating new products, co-branding with premium national and international brands, and partnering with top manufacturers around the world, we’ve created an exclusive range of (Kirkland Signature) products that reflect our members’ tastes and exceed their expectations.”

The approach, from a Costco’s perspective, is to capitalize within a market where they believe an opportunity exists to be a price disruptor to other products currently available. The research includes talking with venders, working with Costco’s long list of approved suppliers, and visiting trade shows—including the PGA Merchandise Show.

The $1.25 Golf Ball That Flew Off Costco's Shelves Is Only Growing ...

The original golf breakthrough came with the introduction of the Kirkland Signature Tour Performance four-piece ball in late 2016. The story goes, Costco was approached by a manufacturer with its own IP on a golf ball design and the opportunity to produce a ball under the Kirkland brand. Independent testing conducted by a third party and Costco’s own internal testing proved the four-piece ball offered exceptional performance. The ball was then approved and shortly after arrived in warehouses. “That’s when things went a little crazy,” says Farmer.

The price of $29.99 for two dozen four-piece urethane balls seemed too good to be true, but in the age of social media and launch monitors, golfers were buzzing, and the balls sold out almost immediately company-wide. Demand and buzz even created a secondary market where the golf balls were selling for 4-5 times their initial price including on eBay. Costco was both shocked and excited, and the ball became the proof of concept that its own line of golf products could be in high demand by members.

The Costco KS1 putter story

Considering the number of options Costco had for potentially producing a golf club, a putter was selected for its relative simplicity and the knowledge that of all the clubs in the bag, golfers love to experiment and test putters the most.

Farmer admitted that he, (a 9 handicap) along with a lot of other employees and members of the board of directors at Costco, are golf nuts themselves, and the putter was an exciting product to develop. It was an attractive product because the company knew it was a category where it could offer the best value and performance comparable to other products on the market.

The Costco buyers approached a well-respected manufacturer in China that also produces putters for a number of well-known OEMs to help develop the KS1. After working through initial prototypes and multiple designs, the wide-body plumbers neck was the final choice based on its popularity and mass appeal.

Farmer made the point that mass appeal is a huge part of the Costco merchandising philosophy because the average Costco Warehouse is 160,000 square feet, and at most, merchandises only 3,700 items per store. When you compare that to other big box stores of similar size, they could carry upwards of 120,000 different items. Fewer products create more value, which at the end of the day, is Costco’s biggest goal.

Costco KS1 putter specs

The specs of the putter clearly reflect the greatest opportunity to offer a club to the largest part of the bell curve for the best possible value.

  • Construction: 100% milled from 303 stainless steel. Also has a 303 insert.
  • Length: 34.5″
  • Loft: 3 degrees
  • Lie: 71 degrees
  • Head weight:  340g with stock 10g adjustable weights. A separate weight kit will be available for 34.99 (online only) and will come with a wrench and adjustable 5g (x2) and 15g (x2) weights.
  • Grip:  Superstroke Countercore
  • Head cover included
  • Right-hand only 

One of the interesting details from my conversation with Farmer concerned the reason the weight kit is being sold separately: “Research shows the majority of golfers don’t tinker with weights and settings of their clubs,” he said. “So to offer the best value, we are making it available online.”

It’s a smart decision that falls right in line with Costco’s directive to offer the greatest value while still creating options for members who are looking for something extra.

Availability & price

According to Farmer, the putter should become available online within the next couple of weeks. They don’t have an exact in-store date yet since pallets (how everything at Costco is moved around, stored, and merchandised) are currently in the process of being built and delivered—but expect to see them around three weeks from now.

The current plan is to have the putters in a select 80 stores to start with the potential to have them expand once the initial volume and sales data is analyzed. Like all things Costco, from mayonnaise to socks, every item has to earn its floor space. But if the putter sells anything like the golf ball, you can expect to see a potential second and third run.

The KS1 putter will be sold for $139.99 USD and the weight kit (available online only) will be a separate $34.99

The putter might just be the beginning…

Toward the end of my conversation with Farmer, the one question I had to ask is if other clubs and balls are on the horizon for Costco and the Kirkland Signature brand. I asked specifically about a rumored three-wedge set, and if they planned to update the current three-piece urethane ball.

Although Farmer was unable to provide specific details about any clubs beyond saying, “we are always working on new products that offer value to our members,” he was willing to say they are excited to see the reaction to the KS1 Putter. As for the three-piece golf ball, Costco is currently going through the testing phase for a potential replacement possibly by the end of the year.

When it comes to offering value, quality, and trust, there really is no other company in the entire consumer goods space that has the ability to deliver on a grand scale like Costco, and the Costco KS1 putter could be another game-changer for this constantly innovating retail giant.

    rick shiels put up a video review of this putter. i guess it is what you expected.

    You’d think quality control could be an issue but given the nature of the milling process, the putters should have good quality.

    303 SS is a great material for putters… just ask Scotty Cameron.

    Me personally, I think the KS1 is a bit chunky for my taste, but I’m sure it feels great.

      Very much a Odyssey looking putter, I ordered one first thing on line and 8 days latter still waiting, but I went into a COSTCO yesterday and they had a pallet full of them…so I got a hands on look….will be sending mine back when it comes without even opening, not anything special until they drop the price to say $79…

    I just want to know where it is made… and by who.. Sean Toulon says it is not made or has anything to do with Odyssey soo… Who??

      May 26, 2020 at 2:25 pm

      Do you really honestly believe any manufacturer would come clean with a ” yeah, we make it” statement?

      Besides there is no Odyssey, toulon etc factory anywhere in the world. A factory is tooled for product, proto types and QC samples are produced, vendor writes a PO ahead of time, production starts, product and marketing material is produced and a way it goes.

      It is just that. I listened to a podcast the other day and it revolved around this putter. It is constructed by same plant with very similar characteristics.

      • Mike

        May 8, 2020 at 2:03 pm

        I believe it’s technically the exact same putter that comes with the Callaway Edge set that they sell, but gets branded as Odyssey with their license agreement.

    You can buy a full set of 10 Callaway Edge clubs from Costco and that includes an Odyssey putter. These must be made for Costco as they are not available anywhere else. A review of them made them sound like a good deal for an average golfer. I hope that I survive this Covid and get a chance to play them. B.

    I don’t understand why you would do a CNC machined 303SS putter and just to put in a machined 303SS face insert. Doesn’t it just defeats the purpose of the CNC precision and you are not trying to affect the impact feel with different material anyways?

    So why did conversation on 4 piece ball stop? They should have talked about why they stopped making the 4 piece ball and why they won’t have the same problem with the putter…or will they?

    They only want to sell you chicken.! And a $65.00 “club” fee.

    Not sure how many members they have now but I have heard they make about $70 million per year.

    The Costco Country Club. Has a nice ring to it…

    $150 OTD for this club seems more in line with buying a club from a traditional gilf retailer. Why would someone make this purchase versus numerous other options from other well known manufacturers? This example of value in no way it compares to that of the original four piece ball that they sold. Thanks Costco but I think you’re whiffing on this one

    May 7, 2020 at 8:05 am

    139.99 in my opinion is not a “real Value”. plus another $35 for weight kit (for those who want it) puts it very in-line with other putters in the big box stores.

    • Homer Simpson

      May 8, 2020 at 10:46 am

      It is a value. Not everyone buys used golf clubs on wrx for a value. I like this site but there are too many club homers and poors trying To flip and make money.

      The only putter line that really puts it in line with are the cheaper Cleveland putters and low-end Odyssey White Hot line, none of which have adjustability features.

      • Brandon

        May 7, 2020 at 9:48 am

        You can find plenty of new past model year higher end Odyssey putters for right around 130 bucks. Got by eye on a stroke lab double wide right now.

        • brian

Wunder: Titleist TSi driver first impressions



Three things I want to address before I kick this off.

  1. “Better, best” will not be addressed. It’s never about that these days only what works for me or you.
  2. I’m not adding TrackMan data to this for one simple reason: It doesn’t matter to me for a first impression. I can get lost in the data and ultimately it confuses my ability to just enjoy the sound feel and look of the driver. Obviously, the fitting was on TrackMan, but in the past, successful drivers for me started with the emotional part. Simply, do I like the thing? Can I look at it? Can I trust it? Can I hit shots with it? That’s it.
  3. When I say “spin this” and “spin that,” it’s always addressing a positive aspect.

On Tuesday of this week, I had the good fortune of visiting the Titleist Performance Institute (TPI in Oceanside, California) to do my TSi metal woods fitting. Won’t get too far into that, but essentially it’s golf heaven in every sense of the word. Like TaylorMade’s Kingdom or Callaway’s ECPC, TPI it’s a gearhead paradise.

Titleist Master Fitter Joey Saewitz (@thejoeysaewitz on IG) was my fitter and after hitting a few balls to warm up, we dug into my gamer driver that I adore.

Current Gamer Spec

TaylorMade SIM (9 degrees @ 8.5). Fujikura Ventus Black 6X (no tipping) 45 inches, D4, GolfPride BCT 58R

I have been constantly messing with my driver between new shafts, lofts, lie, etc. Since I’ve been playing a bit more this month, I’ve had the chance to work on my swing and the driver has been the last thing to come around. I’m working on decreasing dynamic loft through the bag and have not adjusted my driver to match. The point is, I’m hitting the driver solid but have lost a ton of height and spin to keep it in the air.

I’m saying this now because for key metrics I was at a deficiency because of the craftsman not his tools. The SIM I was fit into was/is excellent. So, as you read on, keep in mind that I knew that numbers-wise apples to apples my setup was vulnerable to getting beat out due to my tinkering.


My average numbers these days are are 105-108 mph swing speed, 155-160 mph ball speed, 14-degree launch, and 1,800-2,000 spin. At 43-years-old, when I’m hitting it solid I get a lot out of my driver. IF I’m swinging well, at my low spin, off days can be nauseating with the driver.


TSi3: If two of my favorite drivers 975D and R7 Superquad TP had a baby, the TSi3 would be it. Its flawless appearance-wise. The heel section gives it an onset look that the faders will love and the top line toe section is a bit rounded off to give it an open look without having to crank it open. Not the first time we have heard that but nonetheless, Titleist nailed it.

The face has a cool matte finish that I can’t get into yet, but it frames a white ball excellently.

TSi2: Like the TS2, it has that high-MOI shape, although I will say the top line and transitions are a bit softer on the eye. It’s a driver that looks like it just wants to go high and far. If I wanted to hit something as hard as I could that’s the shape I would look for.

Side note—the black shafts in the TSi3 are almost too cool to even look at—the closest thing to a Darth Vader golf club I have ever seen.


This is where they really figured it out. Titleist drivers in the past to my ear sounded good but not great. There was always an essence of ting that I couldn’t fall in love with. The TSi series fixed that in totality, like all the great drivers on the market in 2020 it has that hammerhead thud that I adore. When you crunch it, you literally hear crunch. At impact, however, it has a more compressiony (is that a word?) feel than its competitors. The comparison would be a one-piece forged feel vs a hollow body players iron. Both feel excellent but there is a difference. You can feel the ball squeeze into the face which I think most will notice and respond well to.

PERFORMANCE—Not going to compare it to my gamer as it’s not fair, I gear headed my gamer to the point of lunacy. I will only comment on what the TSi series did while testing.

TSi3: The biggest standout here was usable spin. I am not a high-spin player by any stretch, so if I can find a driver that gets me 2,100-2,200 consistently when I flush it, it’s a contender. For a player at my speed to sneak it out there with the big hitters, I have to launch it at 14 at 1,700 spin, and hope I’m aimed correctly. What I found with the TSi was I was getting that performance at 2,100-2,200, and if anything only giving up 2-3 yards all while doing it 5/10 times as opposed to 2/10.

What does all that jibberish add up to? Consistency and something I can play with. Is it longer than my gamer? I have no idea, but we will find out. What I know is I hit a bunch of really good shots with TSi3, and after I got going with it, it was point and shoot. Stable? Yes. Long? Yes. Forgiving? Yes. Playable? Yes.

TSi2: To be honest I only hit a few with the Tsi2 as its not my genre of music. What I can say is it feels apples to apples with the Tsi3, launches higher with a bit more spin, and goes really straight. No shocker there. The high MOI category has a bunch of contenders, and in my opinion, it’s a head weight game. Heavy is always better for stability.

The setup I landed on

I was fit into the (D4 SureFit setting 9 degrees @ 9.75, flat) however after testing a bit at home on course and range, I landed on the D1 setting, which I like. For whatever reason, I can play Tsi3 at 8.25 and still maintain height spin and it flew about five yards further.

Final setup

Driver: Titleist TSi3 (9 degrees @8.25, D1 SureFit, 44.5 inches, D4 swing weight)

Shaft: Fujikura Ventus Black 6 X (tipped 1)

Overall, the TSi Series drivers will be VERY popular but not for the reasons you would think. It’s playable, you can hit shots with it, that’s the mark of a GREAT golf club. It’s not all ball speeds and carry anymore in my opinion. This is a driver I can go out and play well with, that’s huge for a hack like me. In my experience, I can’t say that about a lot of drivers I’ve tried to make work in the last four to five years. That’s just me. Lots of great drivers every year but I’m a hard case and finding one that’s just right is a challenge.

Ultimately, for me, the best driver on the market is SIM hands down because it performs in the hitting bay and even better on the course—my hunch is Titleist has something that will do the same.

It’s a beautiful driver that I thoroughly enjoyed getting to know.
