7-Eleven is bringing back a fan favorite and they want you to get as creative as possible.
The chain's popular "Bring Your Own Cup Day" is back, allowing customers to get their Slurpee on in whatever vessel they deem appropriate – and according to 7-Eleven, the wackier the better.
From fish bowls to bike helmets, just about any vessel can be used as a Slurpee drink cup. Customers who make the trek out to their local 7-Eleven, Speedway, or Stripes store on Saturday, Sept. 19, can fill up their cup, literally, with any Slurpee drink flavor for only $1.99.
Because the promotional offer is only available at participating locations nationwide, be sure to call ahead to be sure your neighborhood store is taking part in the fan-favorite tradition.

In addition
to celebrating "Bring Your Own Cup" Day, 7-Eleven is bringing back the bold Mountain Dew Slurpee drink for a limited time.
"Every year, Bring Your Own Cup Day challenges the definition of what a cup can truly be, and our customers never cease to amaze us," Brandon Brown, a senior vice president at 7-Eleven Inc. said in a statement. "For one day only, we’re inviting customers to bring their wackiest cup, fill it with their favorite flavor and show us just how creative a Slurpee run can get."
Whether you're a seasoned pro or getting a Slurpee for the first time, here's everything you need to know about 7-Eleven's "Bring Your Own Cup" day.
How 7-Eleven's 'Bring Your Own Cup' Day works
While creativity is encouraged, 7-Eleven does have some ground rules about the kind of "cup" you can bring in.
According to 7-Eleven, containers must be clean, watertight, leak-proof and able to stand upright within the 10-inch cutout in stores to ensure they fit under the Slurpee drink dispenser.
"Whether it's a trophy, teapot or cookie jar, if it fits, it's fair game," the Irving, Texas-based corporation said. The one-day only offer has a limit of one cup person and will only be available "while supplies last."
