Both Diet Dr. Pepper Target store coupons that are appearing as ad banners on Coupons.com reset to an expiration date of 9/11! The coupons available are $0.75/2 2 liter bottles and $1/1 12 pack. To get these coupons, just head over to Coupons.com and keep refreshing until the banners show up for you. They may be on the side or the bottom of the page.
Some are unable to print them or get a message saying they already did, so even though the date has reset, it may not work for everyone.
Thanks, Totally Target!
