11.11 lands on Wednesday 11 November this year, and Black Friday (27 Nov) and Cyber Monday (30 Nov) are close behind. If your cart is already full, this guide covers the boring-but-useful bits: how GST works on overseas buys, how to spot dodgy deals, what rights you have, and what visitors can claim back.
The dates to remember
- 11.11: Wednesday 11 November 2026
- Black Friday: Friday 27 November 2026
- Cyber Monday: Monday 30 November 2026
- 12.12: Saturday 12 December 2026
Many shops start their sales a few days early, so you may see deals before the actual date. For Shopee and Lazada, we could not confirm full 2026 sale periods and voucher drop times from their own pages. Shopee's 11.11 page advertises a "$111 off $350" voucher, but minimum spend, caps and exclusions were not shown in what we could read. In 2025, Shopee's biggest vouchers dropped from 8pm on 10 November, according to Eventful, but please don't treat that as the 2026 schedule. Check the app.

GST on overseas purchases
GST is 9%. According to IRAS, for goods of S$400 or less per item that are sent by air or post from a GST-registered overseas seller, GST is charged at the point of purchase. If the seller is not GST-registered, no GST is charged at checkout, but you may still pay on import if the total cost, insurance and freight is more than S$400.
Singapore Customs adds that GST relief applies only to air or postal imports of S$400 or below, and not to sea or land imports. If GST or duty is due, SingPost will notify you for postal items, while couriers usually collect it before or on delivery.
Spotting scams
ScamShield says e-commerce scam victims in Singapore lost at least S$16.7 million in 2025. Police advice from past year-end campaigns is still sensible:
- 11.11: Wednesday 11 November 2026
- Black Friday: Friday 27 November 2026
- Cyber Monday: Monday 30 November 2026
- 12.12: Saturday 12 December 2026
Not sure about an offer? Call the ScamShield helpline at 1799 (24/7). If you have paid a scammer, call your bank right away and make a police report.
Your rights if something goes wrong
When goods arrive, check them straight away. The Competition and Consumer Commission of Singapore (CCS) and CASE advise rejecting items that do not match the description, and, if you paid by credit card, raising a dispute with your bank. Under the Lemon Law, goods bought in Singapore that do not conform to the contract can qualify for repair, replacement, price reduction or refund. It does not cover damage you caused, a change of mind, or wear and tear, and it does not apply to consumer-to-consumer sales. For issues with businesses in Singapore, you can approach CASE for help.
Visiting Singapore? Tourist GST refund
Tourists aged 16 and above (not citizens, PRs or pass holders) can claim back GST under the Tourist Refund Scheme. According to the Singapore Tourism Board, you need to spend at least S$100 including GST at one participating "Tax Free" store (up to 3 same-day receipts from that store count) and leave through Changi or Seletar within 2 months. Claim at an eTRS kiosk before immigration, and allow time for goods inspection. Handling fees may be deducted from your refund.
