DALLAS — 7-Eleven convenience stores are starting the fall season with a weeklong Share a Slurpee drink promotion.

The Buy One-Get One Free deal runs every day from September 14 through September 20. Customers who buy any size or flavor Slurpee drink can receive a second Slurpee drink free. The free Slurpee can be the same size as the one purchased, or smaller.

During the Share a Slurpee promotion, both the purchased and free Slurpee drinks count toward the 7Rewards “Buy Six, Get the Seventh Free” drink offer available on the 7-Eleven smartphone app.

To participate in the 7Rewards program, customers must use 7-Eleven’s mobile app, available in the iTunes App Store or Google Play, and register as a member. The member’s unique, scannable barcode and digital punch card are located on the app’s home screen for easier use.

“Slurpee is a fun frozen treat, like a party in a cup,” said Laura Gordon, vice president of marketing and brand innovation. “Lots of our customers bring family and friends with them when they stop by a 7-Eleven store for a Slurpee drink. This offer is not only a great value but also provides a week of opportunities to make new friends with a shared Slurpee. Some might even want to ‘slurp it forward’ and brighten someone else’s day with a free Slurpee.”

Meanwhile, 7-Eleven Canada is bringing back Slurpee Name Your Price Day for the second year, September 16.

The retailer is giving Canadian customers the power to pay what they want for a large Slurpee–100% of the proceeds will go to Food Banks Canada, supporting local food banks in 7-Eleven communities. Last year, the convenience-store chain’s customers raised more than $120,000 (Canadian; $90,511 U.S.), the equivalent of providing Canadians in need with over 360,000 meals.

7-Eleven and Food Banks Canada are challenging Slurpee fans to beat last year’s total. Customers can pay 50 cents, $2, $50 or whatever they want to for the frozen beverage

“We see time and time again how important cause-related initiatives are to our customers,” said Raj Kapoor, vice president and general manager of 7-Eleven Canada, Vancouver, B.C. “We want to thank our Slurpee fans for being so generous last year and now challenge them to raise even more funds this year and have an even greater impact on those in need across the country.”

Dallas-based 7-Eleven operates, franchises or licenses nearly 10,500 7-Eleven convenience stores in North America. Globally, there are more than 56,600 7-Eleven c-stores in 16 countries.
