Coke coupon

It's pretty rare to come across a manufacturer's coupon for coke products, but there is one out there right now.  There is a coupon (HERE) for $2 off the purchase of 4 -12 packs.  It's typical to see 12 packs on sale for 4/$11 lately and with the coupon, that would make them each $2.25.  Not bad.  If you have an abundance of coke points, perhaps you'd be better off just using the "Free 12 pack" coupons?  It seems you can print as many coupons as you want, so if you come across a great coke deal, stock up...and leave a comment here so the rest of us can stock up too!
