Head to Coupons.com and keep your eyes peeled for a very hot Dr. Pepper 12-Pack printable that is good only at Target. It will appear in a banner like the one above either below or beside the standard coupons. Just click on it to print yours, but keep in mind that some of these are printing as a $1/1 Dr. Pepper 12-Pack printable and others are printing as $1/2 Dr. Pepper 12-Pack printable.
Once you've printed yours, another one will become available for Dr. Pepper 2-liters, but again these are printing in several different denominations for different users, including $0.25/1, $0.75/2 and $0.50/1.
Just scroll through the coupons to refresh the screen and change the banners until it appears. This coupon is appearing in various regions at different times, so if it doesn't show up, don't fret; it may appear on another day!
