You have four days to acquire the biggest cup-like object you can find. 7-Eleven is gearing up for its second annual promotion where customers bring their own containers and fill them up with its signature frozen treat. In honor of the Slurpee’s 50th anniversary, the company is doubling down, offering the sweet deal both Friday and Saturday from 11 a.m. – 7 p.m.

Unlike it’s annual free Slurpee day on July 11, the company is charging for the BYOCup Day experience. Customers can fill up for $1.50—the average cost of a medium Slurpee drink. So the key is to bring a larger container, however, it can’t be more than nine inches wide and 11 inches tall, according to a release. It must also be leak-proof, safe, and sanitary. “That means no trashcans or trash bags, kiddy pools or kitchen sinks,” the company said.

Last summer, folks got creative with drums, kettles, fishbowls, helmets, and teapots, said Laura Gordon, 7-Eleven’s VP of marketing. “I can’t wait to see what they bring this year.”

If you can’t find an oversized container, you can buy a collectible 64-ounce mason jar-style cup with a “Slurpee 50” celebration logo for $4.99 (and your first fill of frozen sugar is free).
