I am a B-A-R-G-A-I-N shopper. I recently discovered an even cheaper bread outlet in my town. I get Sara Lee Whole Grain for .75/loaf. THey did tell me they would be going up to probably .90/loaf soon...but that is still a heck of a lot cheaper.
I do my stocking up at Sam's. Meat, chicken, veggies, milk, cheeses, pasta, etc. It's a lot of money at one time...but it lasts the month. I do a fresh produce run every week or so (bananas seem to go rotten REAL quick in my house - I have a ton in my freezer for bread).
I don't get why the government doesn't step in. WE are going to have a lot of very very very poor people with even worse diets b/c all we will be able to afford is Ramen's, Saltine's and water.
