The problem with that is that storage of perishable goods cost money, too, so if you're only feeding a few people buying 10 lb. boxes of frozen foods aren't such a bargain as one would think. I still have a few 5 lb. buckets of chili taking up space from a previous 'Big Giant Bargain' I got a couple of years ago. And, frozen foods have expiration dates, too. Nobyds wants to eat a roast that was frozen in 1982. the portions sold at Sam's Clubs and Costco's are about the right size and at decent prices already for fairly large families, unless you're Mexican Mormons and have 32 kids and another 5 on the way.
MOST People are buying a 2 weeks- months supply to avoid shopping every week.
A bag of fries like that can go fast with a full family. I always run out of my thin fries before my next trip to the grocery. Ever since I started using air frying, it's something I can safely indulge eating more often. But yeah that bag of fries took up alot of freezer space. *L*
I raise my own beef most years, we also raise a hog or two and chickens. I used to have more freezers than the two I have now, and paying for the electricity and maintenance on large commercial freezers just wasn't worth the hassle and expense; I use the space I cleared out now for dry goods. We have a big feast at slaughter time, for the neighborhood and friends with two large smokers going, and I still have more left than I need, so we send a lot home with people. I imagine half of that gets tossed out eventually. I freeze mostly meats, so my result vary; potatoes we bake fresh, but yeah a bag of steak fries is good once in a while.
