The idea behind buying items in a bundle is that in exchange for buying a larger quantity of a single item or a variety of items, the merchant gives you a discount. You give them more business, they give you a better price. That’s how it’s supposed to work, but sometimes this whole system falls apart and prices go up as you buy more.

The phenomenon is called “fuzzy math.” We normally mock Target for doing this, but reader Steve discovered a situation where Amazon is channeling Target and somehow hiked the price on a bundle of games even though you’re buying, you know, a bundle.
