Is there a reward for taking the Tell Subway survey?

Subway rewards customers who take the Tell Subway survey by giving them free cookies. In order to earn free cookies, customers must save their receipts from visits to Subway restaurants and take the survey at TellSubway.com within 30 days of purchase.

The survey takes about one or two minutes to complete and asks questions about the customers' restaurant experiences. After reaching TellSubway.com, customers enter the Subway store IDs on their receipts on the website and then answer the survey questions. After completing the survey, the participant receives a coupon code that he writes down on the indicated spot on the receipt and then returns the receipt to Subway to receive the cookie.
