Fans of 7-Eleven can now wear their loyalty on their sleeves — literally. Slurpee and Big Gulp enthusiasts can now find their favorite products emblazoned on short- and long-sleeved T-shirts, along with other merchandise featuring the 7-Eleven brand logos, including hats, totes, fanny packs — even a coffee-scented air freshener — at 7-Eleven's online shop. Starting Thursday, orders placed using the code 7Collection11 get an 11% discount, but hurry, the offer expires Aug. 31.

Wait, what's that about giant lizards? Anyone who's been in a convenience store late at night has probably seen their fair share of strange characters, but it was broad daylight when a 6-foot lizard decided to chill out in a 7-Eleven near Bangkok. The Asian water monitor — the second-largest kind of lizard in the world — scaled shelves packed with beverages and lingered near the ice machine for more than an hour. No word on whether the valued shopper got a Big Gulp or Slurpee for his trouble.

Long before 7-Eleven made it to Thailand, convenience retailing was born in Oak Cliff, Texas, a suburb of Dallas. In 1927, Southland Ice Co. employee "Uncle Johnny" Green started selling milk, eggs, and bread from the ice dock on evenings and weekends when grocery stores were closed. The small retail endeavor was an immediate success and expanded to all the company's ice docks.

First called Tote'm Stores because customers literally toted their groceries away, the first convenience store was later renamed 7-Eleven in 1946 to reflect its 7 a.m. to 11 p.m. hours of operation. Some of the original Tote'm stores even featured totem poles out front.

In many parts of the world, you don't have to travel far to find a 7-Eleven. As of January 2020, 7-Eleven operated more than 70,000 stores in 17 countries around the world, including more than 20,000 in Japan. By comparison, worldwide there were about 40,000 McDonald's locations in operation in 2020 and some 32,600 Starbucks locations.

The Big Gulp drink, 7-Eleven stores' proprietary 32-ounce fountain cup, is the granddaddy of large-size drinks. First introduced in 1976, the original milk carton-shaped Big Gulp cup nearly doubled the company's fountain business overnight. At the time, it was the biggest cup on the market.

7-Eleven is home to a number of notable worldwide firsts. Not only was it the first convenience store to stay open 24 hours, it was also the first convenience store to sell gas, as well as the first to offer ATMs.

7-Eleven stores began selling Slurpee drinks, then called Icees, in its stores in 1965. The frozen, carbonated beverage was first invented in 1959 by a Kansas hamburger-stand owner. Using an automobile air conditioner, he created a sophisticated piece of equipment that would freeze a carbonated soft drink and serve it in a sherbet-like form that could be sipped through a straw.

The Slurpee name was created in May 1967 during a brainstorming session of the Stanford Agency, 7-Eleven stores' in-house agency. While drinking the product through a straw, agency director Bob Stanford commented that it made a "slurp" sound coming through the straw. In 1994, 7-Eleven trademarked the term "brain freeze" to communicate the painful joy of drinking a frozen Slurpee.

The company entered the wine market with its own private-label wine in 2005. Thousand Oaks, a California vintage, was introduced in five varietals: cabernet sauvignon, chardonnay, merlot, pinot grigio and white zinfandel. Within months, sales of the Thousand Oaks varietals pushed it up to the second-most popular wine at 7-Eleven, only behind mega-brand Gallo. Thousand Oaks is no longer available.

In 2009, 7-Eleven in the U.S. and 7-Eleven Japan partnered to create and introduce Yosemite Road wine, the world’s largest convenience retailer’s first foray into global merchandising. 7-Eleven expanded its private brand wine selection in 2017 with the launch of Trojan Horse brand white wines, adding Voyager Point in 2018 as a more expensive option. In 2021, 7-Eleven introduced Plot + Point chardonnay and pinot grigio, packaged in a screw-top carton. 

For on-the-go wine drinkers, 7-Eleven introduced its first canned wine, called Roamer, in 2018. Roamer is available in chardonnay and rose. Though glass bottles still hold the vast majority of wine sales, canned wines sales have surged in the past few years.

7-Eleven produces some 1,500 private brand items and sales of these proprietary packaged beverages, foods and nonfood items topped $1 billion last year.

Of all its proprietary products, 7-Eleven sells more fresh-brewed coffee than anything else — more than 1 million cups each day.

Last year, 7-Eleven began testing a cashierless store at its corporate headquarters in Irving, Texas. During the pilot, the 700-square-foot nontraditional store is available to 7-Eleven employees.

In recent years, the IRS has partnered with retailers, including 7-Eleven, in the 50 states and Puerto Rico to allow cash tax payments up to $1,000 a day. How does it work?

Every four years from 2000 to 2016, 7-Eleven has hosted an informal "7-Election" poll where customers make their party preferences known by choosing different colored coffee cups either blue for Democratic or red for Republican. In recent years, the company has also offered a third nonpartisan purple "Speak Up" cup that urges costumers to discuss issues that are importance to them. The company skipped the poll in 2020, citing an "unprecedented and financially challenging year for customers," but it isn't ruling out a return in 2024.

7-Eleven Day is an annual promotional holiday held by the company every July 11 in which the retailer offers free small Slurpees from 11 a.m. to 7 p.m. local time. Past years have also included special deals on other items like hot dogs, pizza slices, and yes, Slurpee-flavored cookies. The company suspended celebrations in 2020 and 2021 because of the pandemic but revived it for 2022 to celebrate the 95th anniversary of the company's founding.

7-Elevens vary greatly depending on the location where they operate, with certain items tailored to the local market. In other words: Yes, you can buy sushi at certain 7-Eleven locations.
