Students and office workers, mark your calendars. 7-Eleven Hong Kong has announced a surprise one-day flash promotion at its “7-SI” food counters, offering 10 pieces of siu mai or fish balls for just HK$11 starting tomorrow, July 9, at 2 p.m. The deal includes the chain’s exclusive collaboration with Tam Jai Sam Gor—featuring the popular “Sam Gor口水汁” (spicy sauce) siu mai. Customers can also add a drink for an extra HK$5.
A Budget-Friendly Snack for the Afternoon Slump
The promotion, available only on July 9 from 2 p.m. until closing hours at participating 7-SI locations, brings the cost per piece down to approximately HK$1.1—a fraction of typical street food prices. With Hong Kong’s cost of living continuing to rise, the offer targets budget-conscious consumers looking for an affordable afternoon pick-me-up.
“At HK$11 for 10 pieces, it’s a no-brainer for anyone near a 7-Eleven during the afternoon lull,” said a spokesperson for the convenience store chain. “We wanted to give our customers a reason to smile mid-week.”
The Tam Jai Sam Gor Twist
The highlight of this flash sale is the inclusion of the Tam Jai Sam Gor口水汁 siu mai, a limited-edition variant that marries 7-Eleven’s classic pork-and-mushroom siu mai with the signature spicy, numbing sauce from the beloved noodle chain. Tam Jai Sam Gor, known for its fiery mala broths, has developed a cult following across Hong Kong, and this collaboration marks a rare crossover between a convenience store and a restaurant brand.
Food enthusiasts and Tam Jai fans are encouraged to act fast: the special sauce-topped siu mai is only available while stocks last, and no rainchecks will be issued.
How to Get the Deal
Customers can purchase the HK$11 siu mai or fish balls at any 7-Eleven outlet equipped with a 7-SI food counter. To sweeten the deal, adding any淳茶舍 (Chun Cha She) or 淳茶舍冷萃 (cold brew) 500ml drink costs just HK$5 extra. For those using the 7-Eleven app’s “order and collect” feature, the beverage is free with the purchase.
“Using the app not only saves time but also gets you a free drink—it’s a win-win,” the spokesperson added.
Terms and Conditions
The offer is strictly limited to one day, per single transaction, and cannot be combined with other promotions. Each HK$11 snack set qualifies for only one discounted drink. Items are available on a first-come, first-served basis, and supply is not guaranteed. Full details are available on the 7-Eleven app.
Broader Implications for Hong Kong’s Food Scene
This flash sale is part of a broader trend among Hong Kong food retailers and restaurants to launch aggressive, short-term promotions to lure customers amid a competitive market. In recent weeks, brands like Heytea, McDonald’s, Café de Coral, Sushiro, and ParknShop have all offered limited-time discounts, buy-one-get-one-free deals, and membership rewards.
For consumers, these offers provide tangible relief from inflation, but they also underscore a shift toward digital engagement. 7-Eleven’s push for app orders reflects a growing reliance on mobile platforms to drive foot traffic and streamline operations.
What’s Next?
If you’re planning to take advantage of this deal, set your alarm for 2 p.m. tomorrow and head to your nearest 7-SI-equipped store. For those unable to make it, keep an eye on the 7-Eleven app and social media channels—similar flash promotions are likely on the horizon as the chain continues to test the waters with limited-time collaborations.
