So far i've used 8 of the $1 off coupons. We drink coke zero like crazy. So i only get coke zero or sprite zero. So far just 2 of the stores had 5 coke zero's. 4/13$ and you get 1 12 pack free.. +$1 off coupons4 =9$ for 5 12 packs. So for those who didn't think the $1 off coke coupons worked. they do! Used 8 so far!
