If the sturdy brown box they were delivered in was still sealed with the unbroken packing tape you were not in any danger of losing any golf balls. It's not like TM simply slapped a shipping label on the TP5x box and sent them.
Recieved my 5 TP5x in Washington state today. Luckily didn't lose any of the balls as they were all over the place in the box.
reading comprehension skills - no one had any type of packing tape on any of the boxes.
That means that they could have all been opened - accidentally or on purpose - anywhere along the ling.
I think that my box was opened by someone, because the little cutout thingy designed to hold/display the balls was out of place, and the balls were rolling around, Surprised that the box didn't open anywhere in transit.
I guess that cost of the tape was just a bit too much for the budget
