I never see this posted, and I've missed this deal so many times because of work, and life. You can bring all sorts of crazy cups.

Slurpee® drink fans, it's time to dig through every closet and cabinet! The day when just about anything can be a Slurpee drink cup is back at 7-Eleven, Inc. The brand's annual Bring Your Own Cup (BYOC) Day returns for one day only on Saturday, September 19, when customers can fill up their cup with any Slurpee drink flavor for only $1.99 at participating 7-Eleven®, Speedway® and Stripes® stores.
A fan-favorite tradition where the cup becomes as fun as the flavors inside, BYOC Day gives customers the chance to bring their craziest container and make it the star of their Slurpee drink run. From popcorn buckets and bike helmets to fish bowls and flower vases – the more unexpected, the better!
Creativity is encouraged, but the rules still count: 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.
I've never heard of this. I'm think of stopping by a Starbucks for a large cup of iced water. Drink the water, toss some of the ice, and use the cup to get your $2 Slutpee.
They used to do this for free on slurpee day. I brought a milk jug. I couldn't finish it fast enough, and it turned into juice. I drank it all. I had serious orange diarrhea afterwards. Not worth it.

Be careful out there today guys. Remember, sometimes Speedway, 7-11, etc. may not clean out the inner tubing of the Slurpee machines, causing mold and bacterial growth. Even as the food poisoning may not be super severe (like in cases of eating Chipotle or Taco Bell), side effects from drinking Slurpees can end up making one go to the restroom/bathroom more frequently than individuals who do not partake. I write this as a safety measure, do so at your own risk.
I have some medicine on standby and plan to use an Arby's XL cup to fill up for this promotion.
Happy Bring Your Own Cup Day!

edit: hmm, 10inch height limit. You can definitely do some 40oz tumbler/bottles. maybe find a short 64oz.
edit2: find the largest cambro or rubbermaid food storage container that fits under the spout. lol

The deal states Bring Your Own Cup. The slurpee gods were watching that day.
Lol. It wasn't bring your own cup back then. Around 20 years ago. It was bring any container that fit a certain size, and milk jug fit it perfectly.

Bring any size container. Technically the height should be under 10 inches to fit under the dispenser, but many stores let it slide for this promo.
Regular tub size varies from 3.50 to 4.50 depending on store.
