> it allows people to trade effort for discounts. It doesn't really do that. Instead of going through the hassle (and it is a hassle) of price matching at store A, I can just buy the item at store B at the advertised price. The store offering price matching knows I will do that. They don't care because the guarantee sounds good to the consumer too busy to comparison shop. Unlike, say, coupons, price matching guarantees are not meant to be taken advantage of.
