Yes. I buy meat in bulk. I just bought an 1/8 of a cow and 40lbs of chicken (which i split with someone). Not from the grocery, either one, but its still bulk. then I am in a freezer meal swap so when its meal swap time, i buy my ingredients for that in bulk, usually from Sams, since I make meals for 5 families and each meal is for 6-8 people.
Oatmeal, ground beef when on sale, flour, sugar, baking chips when cheaper than pre packaged, sometimes cold cereal when cheap enough. I don't have a lot of room so its not too often. More so in the summer when all 4 kids are home and it goes fast lol.
