I don't know if anyone knows or not but there is a really cool web site www.thegrocerygame.com
For a small monthly fee she will tell you what food is on sell - what coupons to use - how many to buy and how much you will get it for (sometimes free) it helps me so much with the coupons. Now I don't have to put 2 and 2 together! she does it for me. mention my name if you sign up!
