On August 19 and 20 from 11 a.m.–7 p.m., 7-11 customers can bring any cup they like to any participating store so long as it fits within the designated cutout in the store – to fill up on their favorite Slurpee flavor.

From coffee pots to fish tanks to mom’s favorite vase, Slurpee lovers can choose the way they load up on the iconic refreshment for just $1.50 per cup, and the BYO Cup offer even counts as a punch on customers’ 7Rewards digital punch card.
