Something I learned that helps. Dollar General store for the most part can cut your food bill as well as household cleaning supplies.
Do I care that they don't have a huge variety of Campbell's soup, and the Campbell's Chunky soup variety? Nope, because you can get some variety and at $2.35 for one Chunky in the grocery store, I can get it at DG for $1.97 and when on sale $1.00 a can. (savings $0.38 to $1.35 per can) On the big 25% more Chicken Soup from Campbell's It's $1.50 in the grocery, it's been steadily selling for $1.00 (savings $0.50 per can) and that's just soup. They have a little bit of everything from soup to nuts and it is all well within date of experation.
Some of the best bargains have been with National Brands like Clorox or Lysol and the like. The packaging can sometimes be in French or Spanish but after using it for most of my life I never read the labels anymore anyway as I know the cautions and how to use them.
Bathroom Tissue, a huge chunk of money these days is also much less expensive there. They even have weekly circulars on line, but you get the best deals in the store itself.
These days I have shaved about $50.00 from my monthly shopping because I take my list and stop there first, then hit the grocery for produce and meat which I can afford more of because of smart shopping.
It could be worth taking the time to check Dollar General out.
