"But seriously, how many people are going to find something with a price tag of exactly $20?"
A case of diapers with one magazine coupon $19.24. Close enough
Even if it's $25, they're still not making $10 profit on every $25 order.
i guess they are assuming that a person cant use more then one gift card on there purchase?
Not for sure, they might allow it.
Either way, people who would spend the money anyway (I spend hundreds on Amazon buying things I'd pay more for elsewhere), will end up saving $10 for each of these $20 codes.
