You can take the TellCulvers survey as often as you receive a valid receipt with a survey code from a recent purchase. Each receipt allows for one survey entry at tellculverscom/survey, and typically, you must complete the survey within 48 hours of your visit. After finishing the survey, you’ll usually receive a validation code for a free item or discount on your next visit. However, there may be a limit to how many times an individual can redeem rewards in a given period. Always check the receipt and official rules at (https://tellculverscomsurvey.com/) for the most accurate details.
