On my last visit to Burger King, I noticed a note on my receipt inviting me to take their customer feedback survey at mybkexperience.com. I took my the survey by answering a few quick questions about my visit, and grabbed my Whopper Sandwich or Original Chicken Sandwich for free of cost.

The Whopper and Original Chicken Sandwich are iconic sandwiches from Burger King. Around 250,000 participants spend less than 5 minutes to participate in the burger king customer survey to claim free whopper sandwiches every month.

The Burger King Survey is available in the United States and Canada and can be accessed via the MyBKExperience website, which provides multilingual support in English, Español , and française.
