National Chicken Wing Day is July 29, and 7-Eleven Inc., is celebrating with BOGO deals. The retailer is offering a buy five-piece, get a five-piece free special on bone-in wings, and a buy eight-piece, get an eight-piece free boneless wings deal at 7-Eleven, Speedway and Stripes stores.

The wings come in a variety of different flavors and with zesty sauces, including bone-in spicy breaded chicken wings and hot honey boneless chicken wings.

7-Eleven is also offering an exclusive Celsius flavor—strawberry kiwi. This is the retailer’s second exclusive flavor of Celsius this year.

Earlier this month, 7-Eleven added chicken nuggets to its menu for the first time ever, plus a variety of new menu items including a breakfast skillet taquito, Philly cheesesteak taquito and a personal 5-inch breakfast pizza.

The retailer also collaborated with Hostess on a limited-edition Hostess Twinkies with cherry Slurpee flavored filling. The Twinkies feature “fluffy, spongy cake and lightly whipped Cherry Slurpee-flavored crème filling.”

The treats are available exclusively at select 7-Eleven, Speedway and Stripes stores nationwide through mid-August in a two-count single-serve package.

The chicken wing deals, along with 7-Eleven’s other food items, are also available for delivery through the retailers’ 7NOW app. Additionally, 7-Eleven announced new cashback deals for new and existing 7NOW Gold Pass subscribers as part of its Summer of Cashback program. 7NOW Gold Pass subscribers will receive 10% cashback, while non-Gold Pass members will receive 5% cashback on all 7-Eleven and 7NOW Delivery app orders now through the end of the year.

The cashback is automatically loaded into customers’ digital wallets after delivery completion, does not expire and can be used anywhere within the 7-Eleven/7NOW ecosystem, said the company.
