As of March 2015, the reward for completing a Dunkin' Donuts guest satisfaction survey, known as Tell Dunkin', is a free donut with the purchase of a medium or larger beverage. If the survey is for a Dunkin' Donuts/Baskin-Robbins combo store, the customer can choose a 3-ounce soft-serve cone instead.Continue Reading
The customer must have a receipt, which should have a survey code, to complete the survey on telldunkin.com. To obtain the reward, the customer must complete the survey within three days of his Dunkin' Donuts purchase.
After completing the survey, the participant receives a validation code that he must write in the appropriate line on the original receipt. The receipt then becomes a coupon that he can use to redeem the reward. This coupon is only valid at the store where the original purchase was made, as indicated by the store number at the top of the receipt.Learn more about Corporations
