“The local Wendys had a survey on the back of their receipt that would get you one free burger of your choice with the purchase of any other “premium” burger.
They also had a special on where the Dave’s classic single, considered a premium burger, was $2.
The first time I didn’t even make a purchase, just went into the store, found a receipt near the garbage, filled out the survey, got my code, and then ordered their Asiago cheese chicken burger (their most expensive item) with a Dave’s Single. 2 burgers for $2.”
