The Krystal Guest Survey is an online survey for consumers. Customers us the survey to provide feedback about the service, food and specials they received at Krystal restaurants.
A consumer who participate in the survey can receive a discount coupon to redeem offers such as a free Krystal burger when purchasing a medium fries and drink during a future restaurant visit.
To take the survey, a consumer must visit KrystalSurvey.com and fill in a 12-digit survey code from a receipt, along with the time of visit. The consumer follows the prompts and claims a voucher at the end that entitles him to a coupon for a free burger or sides.
