If you’ve ever wanted to get a gallon-size Slurpee from 7-Eleven for less than $2, then Saturday is your day.

From 11 a.m. to 7 p.m. Saturday, April 11, 7-Eleven stores throughout the country will allow customers to bring their own cup in, fill it up with a Slurpee and pay $1.49 plus tax for it — the standard price for a 22-ounce size Slurpee.

There are some rules though. Whatever “cup” customers bring in must be clean and water-tight and must fit through a 10-inch diameter hole that will be placed near the Slurpee machine at 7-Eleven gas stations.

A cup that size could easily carry a gallon or more. Yeah, that’s a LOT of Slurpee.
