Customers with a printed receipt from Dunkin Donuts with a survey code printed on it can fill out an online survey through the company's survey website. Customers who fill out the survey within 3 days are given a validation code, redeemable for a free doughnut with the purchase of a medium or large beverage.
Dunkin' Donuts opened its doors in Quincy, MA, for the first time in 1950. As of 2015, the chain has 32 kinds of doughnuts, and an estimated 3 million people walk through their store's doors each day.
One of the doughnut shop's chief competitor is Starbucks. Both companies attract a similar clientele and both market a wide range of upscale products and coffee within their brand.
