This is one of the best deals on soda I have ever seen!
Right now you can print a coupon for $1/24-pack or (2) 12-packs of any flavor (Reg. or Diet) Dr Pepper® or Dr Pepper TEN® .
I found it under zip code 30303 (click on local coupons and change the zip code).
Then there is also a coupon for $1/1 12 pack Dr. pepper Target store coupon .
Remember at Target you can use them BOTH!
Buy two Dr Pepper 12-packs 4 for $11 (price will vary by area)
Use two $1/1 Target store coupon here 
Also use $1/2 Dr. Pepper printable coupons  (zip 30303 and look under beverages)
Pay just $1.25 for a 12 pack!
Thanks Common Sense With Money !
