Hong Kong’s favourite drugstore chain is rolling out a rare flash sale that has savvy shoppers reaching for their wallets. Watsons has announced a surprise “Big Discount Day” on Saturday, 16 May 2026, offering all MoneyBack (易賞錢) members an unprecedented 12% off across the entire store with no minimum spend required. The promotion extends both in-store and online, and can be stacked with additional e‑coupons worth up to $110 – plus an extra $50 rebate for those using a HSBC credit card. With everyday essentials, skincare, and household staples all on the table, this one‑day event is a golden opportunity to stock up.
One-Day Flash Sale: No Minimum Spend
Unlike typical promotions that demand a certain purchase threshold, the 12% discount applies to every item – even a single tube of toothpaste. MoneyBack members shopping at any Watsons outlet or via the official website simply need to enter the promo code “12OFF” at checkout to enjoy the automatic deduction. The offer is valid for 16 May only, making it a true “shop now or regret later” moment.
Stack Additional Savings with Coupons and Credit Cards
Beyond the headline discount, Watsons is distributing $110 in e‑coupons to help customers save even more on subsequent visits:
- Skincare & makeup: Spend $150 on eligible skincare or cosmetic products (excluding men’s skincare) to receive a $50 coupon for future purchases in the same category.
- Probiotics & health products: Spend $488 on selected wellness, slimming, or detox items to get a $60 coupon for health products.
To maximise the day’s savings, HSBC cardholders can earn an extra $50 e‑coupon by making a single transaction of $500 or more at Watsons (in‑store or online) before 31 May. Moreover, using a MoneyBack‑linked HSBC Easy Credit Card or Platinum Visa can yield up to 6x MoneyBack points, equivalent to roughly 2.4% cashback – a welcome boost for regular shoppers.
Top Picks for Maximum Value
With the entire store at 12% off, this is the ideal time to invest in premium brands that rarely see price cuts. The editorial team recommends these six standout deals:
- ANITCH Barrier Repair Body Cream (120ml) – discounted to $200.7 after 12% off.
- OLAY Water Sensitive Brightening Set (serum + toner + masks) – just $183.9.

- Salon de Pro hair care – as low as $57.2, with a free Lee Kum Kee oyster sauce when spending $99 on select hair dye products.
- Colgate Total toothpaste – the real star of the show (see below).
Colgate Deal: Free Air Fryer and Fan Worth Over $1,284
Watsons is running a separate promotion from 11 to 17 May that has taken the city by surprise. Customers who purchase five tubes of Colgate Total Professional Gum Care toothpaste (95g or 115g) will walk away with a 2.8L air fryer, a bottle of Virusolve disinfecting wipes, and Wei Jie laundry sanitiser – a package valued at over $685. For those who go big and buy ten tubes, the chain exclusively throws in a 14‑inch ECHOME pedestal fan, bringing the total freebie value to an eye‑popping $1,284. The air fryer and fan have been verified by reporters on‑site, meaning no gimmicks – just real kitchen and home upgrades.
Important Terms to Know
While the offer is incredibly generous, a few exclusions apply. The 12% discount does not cover gift vouchers, infant formula (newborn stage), prescription medicines, vaccination and health check plans, or certain other designated items. All e‑coupons are available on a first‑come, first‑served basis, so early birds will reap the greatest rewards. Full terms can be found at Watsons stores or on the official website.
The Bigger Picture: A Rare Chance to Beat Inflation
As living costs continue to climb in Hong Kong, flash sales like this one allow households to cut everyday expenses without sacrificing quality. By combining the storewide 12% discount, category‑specific coupons, and credit card rebates, a single shopping trip can yield savings approaching 30% on regular prices. For families already planning to stock up on toiletries, cleaning supplies, or health supplements, the 16 May event offers a brief but powerful window to save big.
Whether you are a bargain hunter or simply need to replenish your medicine cabinet, mark your calendar. And with the Colgate free‑gift promotion running all week, there is no excuse to wait.
