Snag Free Fast Food By Completing These Surveys

Here's a hack that requires almost no effort: most major fast food chains will give you free food just for filling out a short survey after your visit. We're talking two to five minutes on your phone and you get a free sandwich, dessert, or BOGO deal on your next order. These programmes have been running for years and most of them are still very much active. Here's the full list.

Heads up: survey offers can change at any time. Always check your current receipt for the exact URL, code, and redemption window before completing a survey.

Burger King — Free Whopper or Original Chicken Sandwich

Go to mybkexperience.com and enter the code on your receipt within 48 hours of your visit. Complete the short feedback survey and you'll receive a validation code that earns you a free Whopper or Original Chicken Sandwich when you buy any size drink or fries. BK surveys consistently run active and are one of the higher-value receipt rewards available.

Checker's / Rally's — Free Sandwich

Find the survey link on your receipt and complete it within 30 days. In return, you'll get a coupon for a free sandwich when you purchase any large drink. The 30-day window gives you plenty of time, which makes this one of the easier surveys to actually redeem.

Chick-fil-A — Free Chicken Sandwich

The survey link is printed on your receipt and is only valid for 2 days after your visit — so don't sit on this one. Complete it at mycfavisit.com and you'll be rewarded with a choice of free Chick-fil-A Chicken Sandwich or Spicy Chicken Sandwich on your next order. For a free premium chicken sandwich, that's a very good two minutes of your time.

Culver's — Free Ice Cream

Complete the Culver's survey within 48 hours of your visit and you'll receive a coupon for a free single scoop waffle cone or vanilla dish. If you're already going to Culver's, this is a no-brainer add-on.

Dairy Queen — Free Dilly Bar

Head to dqfanfeedback.com and enter the code from your receipt within 3 days. Fill in the feedback and you'll get a voucher for a free Dilly Bar on your next visit. Short window, easy reward — make it a habit every time you visit.

IHOP — Free Short Stack of Pancakes

Complete the IHOP feedback survey within 3 days of your visit. Once you've finished, you have 30 days to redeem the reward: a free short stack of buttermilk pancakes. That's a full side dish for a couple of minutes of feedback — worth doing every single visit.

McDonald's — BOGO Quarter Pounder or Egg McMuffin

Visit mcdvoice.com and enter the 26-digit survey code from your receipt. The code is valid for 30 days but the reward must be claimed within 1 week of completing the survey. Finish the survey and get a BOGO Quarter Pounder with Cheese or Egg McMuffin. This stacks nicely with the McDonald's app deals — see our full breakdown of McDonald's app hacks and free food offers to maximise your savings across every visit.

Panda Express — Free Small Entrée

Find the survey link on your receipt and complete it at pandaguestexperience.com within 2 days. You'll receive a reward for a free small entrée when you buy a two-entrée plate. The 2-day window is tight, so complete this one straight after your meal if you can.

Complete the Subway survey using the link on your receipt and earn a free cookie on your next visit. It's a smaller reward than some on this list, but Subway visits add up — and a free cookie is a free cookie. If you eat at Subway regularly, it's worth making the survey part of your post-lunch routine.

Zaxby's — BOGO Big Zax Snack

Head to zaxbyslistens.com and enter the code from your receipt. Complete the short survey and get a BOGO Big Zax Snack — buy one, get one free on one of their most popular menu items. If you're near a Zaxby's, this one is well worth doing.

The Takeaway

All of these surveys take between two and five minutes and most of them are still active and running strong in 2026. The key habit to build: check your receipt immediately after eating, note the survey URL and the expiry window, and complete it before you leave the area or at least the same day. The two-day windows (Chick-fil-A, Panda Express) catch people out most often.

Stack these with loyalty app rewards and you can eat out significantly more often for significantly less. For more ideas, our ranking of fast food meal deals from worst to best will help you make the most of every order.
