Picked up a set of tires at Discount Tire in Bellingham a few weeks ago. During the process the sales guy offered a lifetime replacement should the sidewall or other part of the tire gets damaged and the tire is not repairable. I asked how much - "$23 bucks."
I'm reviewing my receipt right now, and surprise, it's $23 bucks per wheel!! There goes $92 out the window for something I'll never use.
It never occurred to me that this was a per-wheel price, and he never said anything to suggest it. In hindsight, it makes some sense, but it didn't at the time. Yes, I should have checked the receipt, etc., etc., whatever. Keep this in mind the next time someone at one of these tire shops offers your something.
