Same here. Remember grocery stores are done in three days if that.
Even now, you can get some really good bargains in the way of foods that can be stored. We are very careful about shelf-life and end dates, but many foods have an unlimited shelf-life if stored correctly.
One thing we found lately is pizza dough (dry) in a bag. It just requires a bit of water and it makes a decent type of bread. In a pinch you can pan fry it, or even put it on the end of a skewer and cook it over a fire. I think it's $.99 and has a very long shelf life.
I find that every time I go to the grocery, I grab a bag of something to put in the food storage. Seems easy.
