PHILADELPHIA (CBS) — Attention Slurpee fans, Saturday is the day you have been waiting for your whole life!

This Saturday, April 11th, from 11 a.m. to 7 p.m., is “Bring Your Own” Cup Day to all 7-Eleven stores in the United States.

Here’s the deal: customers are able to bring in their own cup and fill it up with their Slurpee flavor.

However, there is a minor catch.

Your cup must be able to fit upright through a 10-inch diameter hole that is located on a cardboard sign that will be placed next to the Slurpee machine.

If it fits, you fill it up!

Also, the cups must be sanitary; so in other words, don’t trying bringing a trash can or a trash bag.

The cost is $1.49!

Once again, the Slurpee promotion is this Saturday from 11 a.m. to 7 p.m.
