I'd reply with the lowest offer I would accept.
I suspect a number of you guys aren't business people in "real life" (I'm not either).
You don't generally get so many customers that you can afford to offend people unnecessarily. Then again, if you aren't really business people in the first place I guess it's to be expected.
My guess would be 99% of the advertised prices are starting prices and the advertiser expects to sell for less. So why be so offended/offensive ?
99% of the buyers don't expect to pay the asking price here. This isn't Amazon for goodness' sake.
I am not offended by it as much as I am annoyed. I have already done the research on pricing and put something up for what I believe to be a fair price. Yes, more often than not, I am willing to work with someone on pricing. But, I started it, I put out a price, a potential purchaser already has an idea of what they are wanting to pay for an item. In the past, I have responded with my lowest price only to have the buyer offer even less. They are trying to lower your starting point so they can negotiate it even further, at least in my experience. I have also just told people to make what they think is a fair offer, just to have them disappear all together.
I get it. But who doesn't want to pay the least for the most ? You ? Probably not. Me ? Definitely not.
But it takes about 15 seconds to hit "reply" and type "Sorry but xxx is the lowest I can go." and move on.
True, but I already posted a price. I guess in my eyes, if you want to pay less than what I am asking, then make an offer. In most cases, I don't have a set bottom dollar price. I try to keep it competitive and will adjust accordingly based on other sales or offers that come in. I just don't buy into that strategy.
But, I will admit, there are ways to ask that question without coming across the wrong way. If someone were up front, much like Shank referenced above, I wouldn't really be annoyed.
