7-Eleven's Bring Your Own Cup Day returns for one day only on Saturday, September 19, 2026. Bring a container that fits the store's 10-inch cutout and you can fill it with any Slurpee flavor for $1.99 at participating 7-Eleven, Speedway and Stripes stores.
The catch is the container, not the price. It has to be clean, watertight and leak-proof, and it has to stand upright under the dispenser. Popcorn buckets, fish bowls, teapots, trophies and flower vases have all passed that test in past years, and the company says the stranger the container, the better.
What you actually save depends on what you carry in. A standard 32-ounce Slurpee cup is roughly 3.5 inches across, so a container that uses the full 10-inch footprint can hold several times that volume for the same $1.99. We ran the geometry below, along with the rules that get containers turned away at the register.
One limit matters before you leave the house: one cup per person, and the offer runs only while supplies last. If you want the widest vessel in your kitchen, go early. Here is everything worth knowing first.

What Is 7-Eleven Bring Your Own Cup Day?
Bring Your Own Cup Day, usually shortened to BYOC Day, is 7-Eleven's annual one-day promotion where the cup itself is the deal. Instead of a fixed-size cup, you supply the container and pay a flat $1.99 to fill it with any Slurpee flavor available in that store.
The event is confirmed in 7-Eleven's own corporate announcement, titled "Think Outside the Cup," published September 9, 2026 from Irving, Texas. The company frames it as a tradition where "the cup becomes as fun as the flavors inside," and it explicitly invites customers to "bring their craziest container."
Brandon Brown, senior vice president of fresh foods and beverages at 7-Eleven, Inc., put the tone of the day plainly in that release: "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."
It is a single-day event, not a week-long sale. The $1.99 price applies only on September 19, 2026 and only at participating stores. After that, the same Slurpee costs whatever your local store charges for the size you buy.
The one rule that sinks most first-timers: your container has to pass through, and sit upright inside, the store's 10-inch cutout under the dispenser. A container that is too tall, too floppy or too wide gets left in the car.
What's Free (and What You Actually Pay)
Nothing here is free in the strict sense, and we would rather say that plainly than dress up a paid deal. You pay $1.99 plus tax for one fill. What makes BYOC Day a genuine value play is the volume that $1.99 buys when your container is larger than a standard cup.
Slurpee cups are sold in fixed sizes, and the price scales with them. On BYOC Day the price stops scaling. That is the entire mechanism of the promotion, and it is why people show up with everything from cookie jars to bike helmets.
Container | Approx. volume | Effective price |
|---|---|---|
Standard 32 oz cup | 32 oz | Store's normal cup price |
6 in wide pot, 5 in deep | About 60 oz | $1.99 flat |
10 in wide tub, 6 in tall | About 260 oz | $1.99 flat |
The middle row is a realistic kitchen option: a six-inch-wide, five-inch-deep container holds close to two standard Slurpee cups' worth for one flat price. The bottom row is the theoretical ceiling of the 10-inch rule, and it assumes a clean, watertight, leak-proof vessel that stands upright unassisted.
Two things change the math in practice. First, one cup per person, so a family of four can run four containers and four $1.99 charges. Second, supplies are finite: 7-Eleven states the offer is "available while supplies last at participating stores," so an early afternoon run beats a late-night one.
How to Claim the $1.99 Slurpee Step by Step
The mechanics take about five minutes, and almost all of the risk sits in step two. Here is the order we would follow.
Pick the container at home. Clean, watertight, leak-proof, and able to stand upright on its own. A vessel that needs a hand to stay up will not survive the dispenser.
Measure the opening. It has to fit inside the 10-inch cutout so it sits under the dispenser. A 12-inch-wide cooler will not clear the cutout no matter how empty it is.
Confirm the store is participating. BYOC Day rolls out at participating 7-Eleven, Speedway and Stripes locations. One phone call to your nearest store takes ten seconds and saves a wasted trip.
Go early in the day. The offer is limited to one day and to available supply. Mid-morning to early afternoon is the safest window.
Fill once with the flavor you want. Any Slurpee flavor in the store qualifies. If the Mountain Dew Slurpee is still on the machine, it counts, and it is only around through October 28, 2026.
Pay $1.99 at the register. One container, one charge. If you want a second container, that is a second $1.99.
Who Is Eligible for BYOC Day?
Almost anyone can walk in and take part, and that is part of why this promotion gets shared so widely. There is no loyalty signup required, no app download required, and no minimum purchase beyond the $1.99 fill itself.
The real eligibility limits are physical and geographic:
Participating stores only. 7-Eleven, Speedway and Stripes locations that opt in. Not every store in the network runs every promotion.
One container per person. This is stated in the official terms, not a store-level judgment call.
Container standards apply. Clean, watertight, leak-proof, upright, inside the 10-inch cutout.
While supplies last. A store that runs out of syrup or ice stops early, and no rain check is published.
Unlike 7Rewards-only offers, BYOC Day does not require a rewards account. If you do carry a 7Rewards or Speedy Rewards account — the programs jointly report more than 100 million members — you can still scan it, but the $1.99 price does not depend on it. There is no points multiplier attached to this promotion in the official terms.
Important Fine Print to Know
The published terms are short, and they are worth reading before you load a fish tank into the trunk.
Date lock: the offer is valid only on 9/19/26. There is no extension, no preview day and no second weekend.
Container standard: must be clean, watertight, leak-proof, and able to stand upright within the 10-inch cutout.
Per-person limit: one cup per person, per the official terms.
Availability: while supplies last at participating stores.
Geography: 7-Eleven, Speedway and Stripes locations that take part. 7NOW delivery does not carry the offer.
Not a souvenir: you bring the container, you take the container. This is not a free 7-Eleven cup giveaway.
Bring a towel and a lid. Leak-proof is the standard, but a full 60-ounce container in a car seat is a physics problem, and the drive home is longer than the walk in.
One more practical note we would add from experience: staff discretion exists at the margin. A clearly clean, clearly rigid container sails through. A cracked bucket, a container with old food residue, or something that wobbles on the counter invites a conversation you do not want at 9 p.m. on a Saturday.
Frequently Asked Questions
How do I claim the $1.99 Slurpee on Bring Your Own Cup Day?
Walk into a participating 7-Eleven, Speedway or Stripes store on September 19, 2026 with a clean, watertight, leak-proof container that fits inside the store's 10-inch cutout. Fill it with any Slurpee flavor and pay $1.99 at the register. No coupon, code or app is required, and the limit is one container per person.
The full terms sit in 7-Eleven's official announcement, and the product details are on the Slurpee brand page.
What size container can I bring for BYOC Day?
Any container that fits within the in-store 10-inch cutout and stands upright underneath the dispenser. There is no published gallon limit — the cutout is the limit. That means a 10-inch-wide bucket with a few inches of depth clears the rule, while a 12-inch cooler does not, even though it is empty. 7-Eleven explicitly lists popcorn buckets, fish bowls and flower vases as examples from past years.
Is Bring Your Own Cup Day available at every 7-Eleven store?
No. The offer runs at participating 7-Eleven, Speedway and Stripes locations, and participation is not guaranteed across the roughly 12,000-plus store network. Supply is also finite, so a store can run out before closing. The fastest check is a phone call to your nearest location on the morning of September 19, or a look at the store list on the 7-Eleven site.
What time of day should I go for the $1.99 Slurpee deal?
Go early. The offer is valid for one day only and only while supplies last, so the safest window is mid-morning through early afternoon on September 19, 2026. The event runs on local store time, which means a 24-hour location in the Eastern time zone starts roughly three hours before a Pacific time zone store. Late-night runs carry the highest risk of an empty machine.
Can I bring more than one container to BYOC Day?
One container per person is the published limit. If four people walk in, four containers are allowed and each fill costs $1.99. What you cannot do is send one person in with three containers and pay a single charge — that is exactly the kind of thing cashiers are watching for on this particular day.
Is the Mountain Dew Slurpee part of the Bring Your Own Cup Day lineup?
Yes, if your store has it. 7-Eleven brought back the Mountain Dew Slurpee for a limited run from August 27 through October 28, 2026 at participating 7-Eleven, Speedway and Stripes stores, so it overlaps BYOC Day on September 19. Any flavor on the machine qualifies for the $1.99 fill.
Details on the return are in the official Slurpee announcement.
What if my local store is not participating in Bring Your Own Cup Day?
You have a few fallbacks. First, the Mountain Dew Slurpee return runs through October 28, 2026, so a regular Slurpee run still lands a flavor that is otherwise limited. Second, 7-Eleven's broader Slurpee Day tradition happens every July 11, when the chain has handed out a free small Slurpee in past years.
Third, if a Slurpee specifically is not available, the same weekend carries several restaurant deals, listed below in our cross-brand comparison.

About 7-Eleven
7-Eleven, Inc. is headquartered in Irving, Texas, and operates, franchises or licenses more than 12,000 stores in the United States and Canada. The company's portfolio includes Speedway, Stripes, Laredo Taco Company and Raise the Roost Chicken and Biscuits locations, and its packaged-goods line runs under the 7-Select private brand.
Slurpee is the chain's signature frozen drink, and 2026 marks its 60th year. The brand celebrated that milestone on July 11 with its annual Slurpee Day giveaway, which featured a limited-time Mountain Dew Confetti Chill flavor and a commemorative anniversary cup design. BYOC Day is a separate, older tradition that trades the fixed cup for whatever customers bring.
The company also runs 7NOW, a delivery app that typically delivers in about 30 minutes depending on the market, and the 7Rewards and Speedy Rewards loyalty programs, which report more than 100 million members combined. Note that the BYOC offer is an in-store promotion and is not carried through 7NOW delivery.
Industry coverage of this year's event comes from trade outlets including CSP Daily News, which ranks 7-Eleven first in U.S.
store count, and NACS, the convenience-store association, which reported the return alongside the Mountain Dew Slurpee news.
