How To Get Free Slurpees At 7-Eleven

National Siblings Day may have passed on April 10, but 7-Eleven has made it a week-long event with its latest buy-one-get-one-free promotion for its new Slurpee flavor. The offer is valid with the purchase of any size Slurpee beverage.

According to the company, Slurpees are better shared with someone else, so who better to share with than your own brother or sister?

"A lot of siblings share Slurpee drinks while growing up, and it's a fun summertime childhood memory," Laura Gordon, vice president of marketing and brand innovation, said in a statement. "With this weeklong buy-one-get-one promotion, brothers, sisters and BFFS can share the Slurpee love, whether they're kids or adult kids remembering how much fun it was — and is — to share a Slurpee drink."

The new flavor is Pineapple Lime, which is being promoted along with Trolli's Sour Brite Sloths gummy candy.

During the promotion, both the purchased drink and its free sibling will be counted toward the convenience store's "Buy Six, Get the Seventh Free" drink offer, which is available through the 7Rewards program on 7-Eleven's mobile app.
