How many times do you either not ask for a receipt or just throw it away without looking at it? Well, if you love Dunkin Donuts like I do, then you'll want to hold on to that receipt! At the bottom of every receipt, you can get a FREE donut by simply listening to a short survey (automated) about your visit. At the end of the survey, they'll give you a code to put on the receipt and your next donut is free!! I can't remember the last time I paid for a donut!! So, the next time you buy something at the drive-thru be sure to look at your receipt.. you'll never know what you're missing!
