I found this site a month or so again, but had a friend (thank you Denise) remind me about it. It is AWESOME!!!! She tells you what to stock up on (based on the weekly sales) and how much to buy for your family. It's a NO- BRAINER. Check it out! http://myfoodstoragedeals.com/
She also has a blog with TONS of useful information.
