Hong Kong supermarket chain Wellcome is ushering in the spooky season with a wallet-friendly Halloween treat. From Sept. 29 through Oct. 5, 2026, shoppers can get a 500ml bottle of Fanta’s limited-edition Mixed Berry soda for just HK$1 — a HK$10 value — when they follow a few simple steps. But with only 2,000 bottles available, preparation will be key.
The offer is part of Wellcome’s “Must-Grab Tuesday” promotion, a recurring limited-time series designed to reward in-store shoppers. To join, customers must comment “GRABTUE” on Wellcome’s designated social platform. Those who do will receive an electronic exchange voucher. Then, in a single transaction, they need to buy any room-temperature beverage — excluding room-temperature milk and alcoholic drinks — and present the voucher at checkout to get the Halloween-themed Fanta for a dollar.
What Makes This Deal Interesting?
Seasonal limited editions are a proven draw for casual shoppers and foodies alike. Fanta’s Mixed Berry flavour was created specifically for Halloween, and once the promotion ends, it may not be restocked. For fans of novelty snacks and drinks, this deal is as much about tasting something uncommon as it is about saving money.
The activation also has a social-media friendly twist. Participants must act quickly: once they tap “go to redeem,” a 20-minute countdown begins. The voucher barcode must be scanned at the cashier within that window, or the offer expires. Shoppers also need to enable messages from strangers in Facebook Messenger, since the e-coupon is delivered through that channel.
Key Rules and Limits
- Total stock: 2,000 bottles, first come, first served.
- Individual limit: one voucher per customer; each voucher can be used for one soda.
- Eligible purchase: any room-temperature beverage, excluding room-temperature milk and alcohol.
- Redeem window: a 20-minute countdown starts when the voucher is activated.
- Not valid at: Wellcome online store, Market Place online store, or yuu online shopping.
Should Shoppers Try It?
For anyone who enjoys seasonal sodas or wants an inexpensive, playful addition to a Halloween gathering, this deal is almost a no-brainer. At just HK$1, it is a low-risk way to sample a limited-edition flavour. The scarcity could also make it a fun mission for families and friends who follow local food news.
That said, the promotion requires a little advance planning. Since the e-voucher is only distributed through the designated platform, customers should check their Facebook Messenger settings before joining. Those who want to avoid disappointment should also be aware that the 2,000 available bottles are expected to disappear quickly.
Limited-time supermarket offers like this also reflect a broader trend in Hong Kong’s food retail sector. Retailers are increasingly blending social engagement, app-based mechanics, and in-store footfall into a single experience. For the savvy customer, the reward can be as simple as an ice-cold Halloween soda for a single dollar.
Shoppers should remember that promotional details may change without notice, and Wellcome’s official channels remain the best source for the latest rules. Before heading out, it may be worth checking that local stores are participating and that the relevant messaging settings are switched on.
