Here is a great coupon to use at CVS. It’s for a BOGO Free Coca Cola Printable Coupon. The coupon is good for 20 oz bottles of Diet Coke or Caffeine Free Diet Coke.
And, if you still have the $1/1 Diet Coke coupons (no longer available) I posted a couple of week ago you can do this deal:
Buy 2 Diet Cokes
-(1)BOGO Free Coke Printable Coupon
-(1)$1/1 Diet Coke Printable Coupon
2 Free or Close to it depending on the price of the soda
