I used to have a roommate who thought he was a really savvy shopper. He'd come home with a 50-count bag of frozen chicken breasts because "it was such a steal." But I always thought the purchase was quite short-sided because he only focused on the volume he was getting for his buck, completely ignoring total cost of ownership. Time and time again I'd watch him throw out much of the uneaten chicken, because um, who in their right mind has the stomach for 50 frozen chicken breasts? How's your price per unit now buddy? Not to mention it wasn't fresh meat so he was consuming an inferior product. And he was ignoring the amount of energy being gobbled up by that behemoth bag in the freezer, as well as how that space could have been used for something else.
