Nothing is inherently bad that he purchased, just not thought out at all. It is a series of "good deals". We like yogurt. Did we need 20 containers of Yoplait because they were 10 for $5, or would 10 have been plenty for this week? ( I also have been buying Greek yogurt and not the overly sweetened versions which he bought.) He bought two huge bags of Malt O Meal cereal at 3 for $7. I buy smaller boxes, that I know will actually get eaten, for under $2. Chances are 1/3 of each of these bags will get stale before DD2 gets to eating it all. Bulk buying is different for different families. Sure, 12 years ago with two teens and a preschooler, buying huge cereal bags was a no brainer. Today, it is nonsense.
The rest was like this as well. Five items of something. Ten of another, but other than the ribs which we will get two meals out of, and two frozen pizzas, nothing will make complete meals. I'm still going to need to shop this weekend, once I do a think through what he bought, to round out with protein and vegetables. I guess his shopping isn't all bad. We had a nice meal of ribs, baked potatoes we already had on hand, and baked beans. On the truly bright side, it beats a gambling habit.
