Monday is Free Slurpee Day. Here’s how you can get yours at the local 7-Eleven.

Since 2002, 7-Eleven, the world’s largest convenience store operator, has been celebrating its birthday on July 11 (I’m not afraid to admit that it took me a while to figure out the whole 7/11 thing) by offering free Slurpee drinks to customers throughout the country.

But the chain is stepping it up this year, thanking its guests for their patronage in a bigger way.

“Customers have often referred to 7-Eleven Day as Slurpee Day, now we are too, and enjoy $1 deals on fan-favorite snacks like Big Bite® hot dogs and pizza slices from July 1 – 11. To celebrate Slurpee Day, participating 7-Eleven, Speedway, and Stripes stores will feature a limited-time-only mystery Slurpee drink flavor called ‘What the Fanta,’ but every Slurpee drink flavor is available for customers’ enjoyment,” the company said.

7/11 Website

7-Eleven was founded in 1927 in Dallas, Texas. They are offering this bigger-than-usual promotion in honor of its 95th birthday which falls on Monday, July 11.

Rio Linda/Elverta’s 7/11 Store is located at 348 Elkhorn Blvd.

So… What’s the catch? Customers need to be a member of 7REWARDS, the loyalty program found in the 7-Eleven app. Only one coupon is allowed per 7-Eleven account. To redeem, members can scan their 7-Eleven app, or enter an alternate ID at checkout.
