We have started buying a few items in bulk from Sam’s Club usually. On the last trip we bought 2 BIG cans of Tomato Sauce for less than $3 each and a BIG can of diced tomatoes for less than $3.
I opened each can and seperated the contents into freezer bags and froze them for future use.
These have worked out really well so far. When I need to use tomato sauce or tomatoes I just grab a bag. And buying it this way is sooooo much cheaper. I got about 5 meals from the sauce and close to 20 from the tomatoes. Woo Hoo!
