I think part of the question would be, how often are they actually used?
I don't think I'd say we use ours a lot, but . . . we buy most of our meats at Sam's Club, then seal & freeze individual ribeye steaks, country style ribs, even hamburger patties. We buy one of those big Sadler sliced briskets and I trim the fat and seal & freeze 12 oz. packages of it. Saturday, I bought two 12 oz. cartons of already shelled Purple Hull peas at the local farmers market, sealed and froze them. When we open a sack of potato chips or corn chips, I re-seal the top of the package. We buy other meats at Fischer's in Muenster, repackage, seal and freeze things like the cutlets we use for chicken fried steaks.
Incidentally, we both like blackeyed peas almost any way, but our preference is for young (green?) ones and I simply cannot find such in the stores. Dried ones are plentiful and canned ones, of course. But even the canned ones "with snaps" are all older, mature, and/or made from dried. However, last year at our local farmers market, a couple of places had the shelled purple hull peas. I guess it's a pint container, but weighs about 12 oz.; $5 each. And they are very young, fresh peas. I only bought 2 Saturday, but we recently finished the ones we bought last year, and I'll definitely be buying more. They keep very well, sealed and frozen.
