I came across my very first Smashburger coupon yesterday. Found it on the back of my grocery store cash register receipt. “FREE Smashburger with the purchase of another Smashburger entree of equal or lesser value.” This came from the Rainbow supermarket in Eagan, Minnesota and is valid at the 1270 Promenade Place Smashburger location. Usually, when register receipt coupons show up in one area, they are also being offered in other regions. Check the back of your receipts! If you find Smashburger coupons, please let us know so we can pass it along to other CheapoLifers.

This coupon offer valid throughout September, October, November, and until December 31, 2011. Most Smashburger restaurants will be open regular sale hours on Columbus Day (Monday, October 10) and Halloween (Monday, October 31.)
