Don’t forget Grocery Outlet stores, typically a good source for things you never see in discount stores. I regularly find cheese that is elsewhere $5 - 7 a pound, and there it’s blow out priced at a $1 a pound. I just today got Kerry Gold cheddar for $1.00 a pound. Now I have almost 50 years of thrift purchasing for huge restaurants and commissaries, I know my way around food costs.
P.S. cook your own food, cheaper and healthy for you and your family.
