take the codes printed into the cases or caps enter them in at coke.com or text them then every 35 points you can get $1 off a twelve pack. i thnk this is the best coupon the have. entering in codes got alot easier also. 12 packs are 10 points, cases are 20 points, and caps are three. the coupons are good for three monthes and you can print them at home.
