I suspect a lot of the BOGO deal structure is to exploit the consumer who intentionally buys only what he can use. Supermarkets here have gotten big on "buy one get (1, 2, or even 3) free" for large meat packages (racks of ribs, for example), but keeping the price tag high-- say $12 per pound. If you fully exploit the offer, you're effectively paying a bargain $3 per pound, but that requires a lot of fridge space to deal with four big packs of perishable meat. The consumer who says "I only need one or two" is being gouged for NOT wanting to throw rancid leftovers away. A similar related gimmick are the "buy N, save $M deals." If you buy any ten of a pool of random items, they knock off $10 from the order, but if you only need 9, or 1, you're paying full price. There's definitely been a swing from "everyday low prices" to "gimmicks and games." Everyday low price became "3-day sale" became "only with club card" became "only if you install our terrible app and explicitly select you want the promotion ADDED to your club card." I think the ultimate goal is to get where they can advertise aggressive discounts, knowing they don't have to give them to anyone but the people most willing to jump through hoops to get them.
