I like those four packs for cooking; if I'm not drinking wine (because of this diet, for example) I don't want to open a bottle to use a little in cooking and then let the rest of the bottle sit there and get old. And if I'm on a diet I don't want the temptation of not wasting the wine by letting it get old. ;-D Those little bottles end up being just enough (like if I buy a fresh salmon today to make smoked salmon and use wine in the brine, one of those bottles is just right).
I keep thinking of more places I'll have the change the accounts. I'm making a list.
