It’s the whole “couponing is only trashy if you’re poor” mentality.

For the rich, couponing is a game. See how much you can get, for as little as possible. You have the storage space for it, so you’re not worried about excess or waste. All you care about is gaming the system to see what you can get. You had to buy 18 months worth of laundry detergent to get the discount? That’s fine, cuz you have space for it at home. And your basic necessities are already covered, so the coupons don’t need to be for staples that you’ll use quickly or regularly.

For the poor, couponing is a necessary evil. You’re eating chicken every day this week; Not because you really like chicken, but because it’s what you had a coupon for. And now you need to eat it before it goes bad, because you need the space in the fridge for this week’s coupons and you can’t afford to simply toss it out.
