I agree, about the difficulty in shopping for products for 'two', as opposed to shopping for the Family packs. I have noticed though, that in the last couple of years, more and more products are being offered in the 'two-pack', or at least a smaller version of the large-quantity size product.

The biggest difference, for us, is that we don't buy a lot of what I call 'covenience' foods, or snack foods, now that we are empty-nesters. Whenever our grandchildren come over, to spend some time, we usually make a shopping trip, for items we never buy. They like some pretzels, or an ice cream cone, or something like that, and we just don't have that sort of thing around. I also cook differently, more simply, now that it is just the two of us, with an eye toward serving foods that contain less fat, and less sugar, and less empty carbs. Lots of fresh fruit, and veggies, and lean meat and fish.
