To participate in the Kroger Feedback Survey at www.kroger.com/feedback, you must meet certain eligibility criteria. First, you need to have a recent Kroger receipt with a survey invitation code. This code allows you to access the survey online. Participants must be at least 18 years old and legal residents of the United States. The survey is not open to Kroger employees, their immediate family members, or affiliates. Additionally, each receipt code can only be used once, and the survey must be completed within seven days of the receipt date to be eligible for rewards, such as digital coupons or sweepstakes entries.
