THere are more cost effective ways to stock on food... maybe not the greatest choices, but they are calories if ever needed to be called on.
Cans of stuff like ravioli, dried noodles, spam, etc.. find it on sale, but a few more cans. I'll last practically forever and doesn't cost 60 dollars for 12 freekin meals. Years from now when I have to throw it away, I won't be out all that much really so who cares.
I’d suggest putting more thought into the process if you really want to prepare. It takes a great deal more food than you would think.
Store what you eat, eat what you store and you don’t throw anything away.
