Go to Sonic’s Tater Taunt page and create a Taunt……something like “this Tater is going to kick your booty” or “you just got schooled by a Tater” LOL
After you create your taunt hit send, I used url and then hit copy. Then close the box and it will ask for your email address to send you a coupon!
The coupon I got was for a $.99 Route 44 soft drink (44oz) which is about half price. Not sure if there are other / different coupons that they will offer as well.
