Wingstop is giving the first 500,000 people two free chicken tenders each, which is a $5.99 value. After entering your info, you'll have to authenticate your phone number. I used my Google Voice number and it worked just fine. Then, you'll be shown a promo code to redeem on your next order at Wingstop.com or through their app.
According to the fine print, this website will give out a maximum of 100,000 coupon codes per day. Codes will be available through 3.31.25, until they hit their 500,000 limit. You'll also have to make a purchase in order to use the code, but there's no minimum requirement so you can get the cheapest thing on the menu – like an extra side of sauce – and still use the coupon.
