11.11 sale Singapore 2026: dates to check and a price log

As of 17 October 2026, no platform or organiser page we could read confirms the 2026 dates of the 11.11 sale in Singapore, Black Friday or 12.12, so this dated calendar lists none of them as fact. The names point to calendar dates: 11 November 2026 is a Wednesday, 12 December 2026 a Saturday and, by the usual convention of the Friday after US Thanksgiving, Black Friday is Friday 27 November 2026. None of those is an announcement by a Singapore platform or retailer. This page lists what is confirmed instead: public holidays from the Ministry of Manpower (MOM) and what the Competition and Consumer Commission of Singapore (CCS) says about “was” prices, countdown timers and add-ons. Recheck each seller’s own campaign page on 26 October, 2 November, 10 November, 23 November and 7 December 2026, and add a date only after opening a page that states it.

Anything not read from an official page is labelled as our inference or as unconfirmed.

What should I do between now and 11.11?

Use the weeks before 11.11 to build your own price record, since a “was” price on a sale page is the seller’s claim. The method is explained in the year-end total-price check. Here it is on the calendar; this is our suggested schedule, not an official one:

• Saturday 17 October 2026, or the day you read this: choose three to five items you may buy. Screenshot the price, delivery fee and warranty terms for each, with the date visible.
• Saturdays 24 and 31 October and 7 November: repeat the screenshots.
• Monday 9 November: the Deepavali public holiday for people whose rest day falls on Sunday 8 November, so check opening hours before visiting a shop to try an item.
• Tuesday 10 November: take a final baseline screenshot and note which voucher, delivery and return terms each seller shows.
• Wednesday 11 November: for each item, screenshot the final payment page, showing the total after delivery, add-ons and vouchers, before you pay.
• Friday 27 November and Saturday 12 December: if a seller you use runs a Black Friday or 12.12 sale, repeat the same checks against your log.

If an item comes from an overseas seller, see how GST applies to overseas online purchases before comparing totals. When an item arrives, use the return window well: the home-trial test plan sets out three tests for the first week.

What do CCS’s guidelines say about “was” prices, timers and add-ons?

These are CCS’s own words, read on 17 October 2026. They describe what CCS expects of sellers; they do not show that any particular 2026 sale follows them.

• Headline price: “Suppliers should ensure that any unavoidable or mandatory charges (e.g. taxes, surcharges, service fees, etc.) are included in the total headline price.”
• “Was” prices: sellers “should ensure the discount or price benefit offered is genuine and provide a valid basis for the discount or comparison.” CCS adds: “Suppliers are also encouraged to keep records of past sales and prices to prove that the past prices and discounts given are genuine.”
• Time limits: “suppliers should state the time period clearly and accurately to avoid misleading consumers.”
• Add-ons: “Suppliers are also encouraged to adopt an ‘opt-in’ or ‘opt-neutral’ approach to bring consumers’ attention to optional add-ons.” That is encouragement, not a flat ban on pre-ticked boxes. CCS’s page on dark patterns (last updated 9 October 2026) describes “Sneak Into Basket” as “When businesses add items or subscriptions to your shopping cart without clearly telling you (e.g. using pre-ticked boxes), hoping you won’t notice it before your payment.”

CCS’s dark patterns page also says of false urgency: “CCS is concerned if there is no reasonable basis for businesses to make urgency or scarcity claims. Businesses must be prepared to back up any urgency or scarcity claims made.”

A dated case. On 8 December 2025 CCS published “CCS Takes Action against Courts and PRISM+ for Misleading Website Features”. It says “PRISM+ used fake countdown timers and misleading stock indicators to pressure consumers into purchases”, and lists the features as “fake countdown timers, misleading stock indicators, unsubstantiated shortage claims and inflated discounts e.g. ‘Up to 67% off’”. It says Courts “automatically added unsolicited items into consumers’ shopping carts”. CCS’s media release on the case adds that the timers “served no technical function” and “simply reset after reaching zero without affecting the checkout process”. According to CCS, both retailers gave undertakings, and the case register lists the investigation as closed.

Our inference: a countdown, a stock counter or an “up to” discount on a sale page is a claim the seller must be able to back up, not proof of a good price. Your own log and your own decision date are the better guide. For ratings on a sale listing, see what CCS found about fake reviews.

How do I tell a real discount from a headline one?

Our suggestion: compare the checkout total with your lowest logged price, not with the crossed-out price. An illustrative example, with fictional figures: on your five log dates you recorded an item at S$499, S$499, S$489, S$499 and S$499, all with free delivery. On the sale day the page shows “was S$599, now S$449”, plus S$12 delivery.

• Headline saving: S$599 − S$449 = S$150.
• Real total: S$449 + S$12 = S$461.
• Saving against your lowest logged price: S$489 − S$461 = S$28, about 6%.

If a pre-ticked add-on had pushed the total higher, untick it and recheck. If the final total is not below your lowest logged price, the sale has not saved you money on price alone, whatever the page says. Before you check out lists what to save in case an order goes wrong or a price or promise turns out to be misleading.

What should I recheck, and when?

• Monday 26 October 2026: open each platform’s own campaign page and note any published 2026 dates, with the date you checked, and whether voucher terms, delivery cut-offs and return terms are published.
• Monday 2 November 2026: repeat, and confirm dates for 11.11 before the week itself.
• Tuesday 10 November 2026: confirm the final dates and your baseline prices.
• Monday 23 November 2026: check for Black Friday and 12.12 dates from each retailer you use.
• Monday 7 December 2026: check for 12.12, Christmas and Boxing Day dates, and for any change to MOM’s public holiday list.
• Saturday 2 January 2027: the year-end window is over, so revise this page to the past tense or retire it, and recheck the 31 December 2026 and 1 January 2027 NRIC dates on MDDI’s page before repeating them.

Add a date to this calendar only when a platform or organiser page you have opened states it, and record the page and the day you opened it.
