The point is it's irrational behavior. And we all do it.

It's burning $5 in gas and $20 in time to go to a store further away and save $25 on a sale item. And then proudly bragging "I'm not like those idiots who pay full price!"

OP didn't find a record...he found a $1300 arbitrage, then decided to spend the proceeds on the record by keeping it.

In other words, this is why selling stuff to consumers is a nightmare.

You have to trick them into believing they "won one over" on everybody else, via discounting and promotions, no matter if ultimately they're the ones losing by spending hours of their time jumping through hoops on a product that they legitimately value at full price.
