The coupon spitter gave me a $2 of any 2 Gold Medal candy coupon. Gold Medal is the brand of old-time candies like gummy bears, etc... They are on sale right now for $0.99 a bag so I got 2 bags for free.
At the bottom of the receipt was another coupon for $2 off 2... so I walked out with 4 bags of gummy worms with no OOP cost! (They didn't have what I originally went for so the 2nd transaction was literally...
"That'll be $2.09."
"I have a coupon."
"Here's your receipt."
