In honor of the 50th birthday of the convenience store's flagship item, 7-Eleven is offering customers a deal to fill up any container for only $1.50.
"Bring Your Own Slurpee Cup Day" or #BYOCUPDAY is taking place on August 19th and 20th from 11AM to 7 PM.
7-Eleven customers can bring in any food-safe, watertight cup anywhere up to 10 inches in height (with no restrictions on width,) and fill it up for only $1.50.
The convenience store chain is also using the event to promote its 7Rewards app, which gives users their 7th Slurpee free with the purchase of six others. Text* BYOC to 711711 to download the 7-Eleven® app and join 7Rewards.
