At Stop and Shop I bought 21 12oz v8 fusions for FREE after coupons. They were 1.50 each, and I had .75 coupons that doubled. You can find the coupons at gas stations and CVS, and maybe other places?
Then I went to CVS and got 4 mentos gums, 2 dentyne 3 packs of gum, 10 bags of nuts, 5 colgate toothpastes, 2 packs of m&ms's. After my coupons and 10 ecbs, I paid .03 and got back 4 ecbs, woohoo!
