The Piggly Wiggly deal uses a coupon on the front of their ad to get the 5th one for free, while Winn-Dixie's done with the reward card. I haven't been to Winn-Dixe. But, i've just come back from Piggly Wiggly and their deal is on the full line of Coke products. Much better than the limited deal when CVS had this deal last week. I stood up there for 5 minutes trying to decide which 5 to get -

. All varieties of Coke, including cherry Coke Zero, which I hadn't seen before. Also the regular, zero and diet varieties of Fanta, Vault, Barq's Root Beer, Nestea, Delaware Punch, Sprite and probably some others that I didn't notice because they were sold out on the soft drink aisle.
Also, don't forget your 44-ct packages of Chinet Casuals at Piggly Wiggly, if you can find some. My local store only had 2 packages left and I found them abandoned in odd places around the store. perfect for me because I just had 2 coupons anyway. They're $0.99 and the coupons are for $0.50, making them $0.49.
