SavingStar has a sweet coupon that if you buy $15 worth of Pepsi Max products, you get $5 back into your Savingstar account. My Frys (Kroger) store has Pepsi 2 ltr for $.89 wyb 10, so I will be sure to get $15 worth. This offer is good until November 30th, so hurry on over to Pepsi Max Facebook page and get the deal.
If you don't have an account with Savingstar yet, you'll need one to get their awesome coupons. Just add your store loyalty cards, and e-clip their coupons. When you reach $5 in savings, you can request a payout in prizes or cash.
