Shopee 11.11 vs Lazada 9.9 vs Amazon Prime Day: SG 2026 mega-sale calendar

Updated: September 2026.

TL;DR verdict

For a Singapore household planning 2026 shopping around the three biggest cross-marketplace tent-poles, treat Lazada 9.9 as the September opener for consumer electronics and small home appliances, Shopee 11.11 as the November peak for sitewide vouchers and fashion, and Amazon.sg Prime Day (mid-July annually, members-only) as the tent-pole for imported US-brand consumer tech, beauty, and household consumables. The single deepest sitewide voucher windows across all three platforms historically open in the first two hours of Day Zero midnight and reappear at 12pm, 8pm, and 11pm live-stream slots. If you can only pick one to plan around this year, pick 11.11 because sitewide voucher depth and cross-category breadth peak that day.

The three tent-poles and why they matter for a Singapore basket

Singapore's calendar of online mega-sales sits inside a wider retail turnover base of just over SGD 4 billion a month, and online-only sales are a meaningful and growing slice. The Department of Statistics Singapore reported in its July 2025 Retail Sales Index release that "online sales made up an estimated 12.6% of the total retail sales value in July 2025" (source: Retail Sales Index July 2025, Department of Statistics Singapore, released September 2025). That share drifts up around September, November, and December as mega-sales pull spend online and away from bricks-and-mortar.

Amazon's 2024 Prime Day globally set a record. Amazon's newsroom press release stated that "Prime Day 2024 was the biggest Prime Day event ever, with record sales and more items sold during the two-day event than any previous Prime Day event" (source: About Amazon newsroom, July 2024). Independent tracking from Adobe Analytics on the November-into-December window put US Cyber Week 2024 at "a record USD 41.1 billion in online spending, up 8.2% year-over-year" (source: Adobe Analytics Cyber Week 2024 recap, December 2024). The macro signal is clear: sitewide voucher windows are getting deeper, more concentrated, and more calendar-driven every year.

Lazada 9.9 (early September): what it wins on

Lazada 9.9 lands in early September and is the year's opening bell for Q4 shopping. Historical positioning: strong on consumer electronics (LazMall brand storefronts like Xiaomi, Samsung, Dyson, Philips), small kitchen appliances (air fryers, kettles, blenders), and everyday household consumables. LazMall vouchers on Day Zero usually stack with bank-card promos (historically DBS, UOB, and Citi have run 9.9 tie-ups in Singapore).

Category strengths where 9.9 tends to beat 11.11 in Singapore: LazMall electronics brand stores tend to load their heaviest LazMall-exclusive promo codes for 9.9, because 9.9 is where the electronics category owns the calendar before it gets buried under the 11.11 apparel wave. If you are buying a mid-tier air fryer or a name-brand small kitchen appliance, 9.9 is usually where LazMall-brand-owned pages beat their own 11.11 price.

Shopee 11.11 (November 11): what it wins on

Shopee 11.11 is the deepest sitewide voucher day on the Singapore calendar. Historical shape: sitewide vouchers open at midnight, more waves at 9am, 12pm, 3pm, 6pm, 9pm, and 11pm. Fashion, beauty, women's apparel, and cross-category impulse buys dominate share of basket. Shopee Live is the biggest single traffic driver on 11.11, with countdown drops that release limited-stock promo codes.

Category strengths where 11.11 typically wins over 9.9 or Prime Day in Singapore: apparel (women's fashion, activewear, shoes), general beauty (masks, skincare basics, hair care), and lower-ticket general merchandise. If you want the widest cross-category discount surface in one day, 11.11 is the day.

Amazon Prime Day (mid-July): what it wins on

Amazon Prime Day is annual, members-only, runs on Amazon.sg in Singapore, and locks pricing behind a Prime membership (currently SGD 2.99 a month at the standard tier). It is uniquely strong on US-origin consumer tech (Kindle, Fire tablets, Echo, Ring), imported US-brand beauty (CeraVe, La Roche-Posay grey-market listings), and grey-import audio (Bose, Beats, Sony premium). The advantage vs Shopee 11.11 is depth on single US-brand SKUs that Shopee and Lazada carry inconsistently. The disadvantage is narrower breadth, higher-ticket average basket, and the Prime membership gate.

Where the price differences come from

Three mechanics drive the visible price gaps between the events. First, platform-funded vouchers: Shopee and Lazada subsidise sitewide voucher codes out of their own marketing budget for Day Zero, which is why the deepest sitewide codes only exist on those two dates. Second, brand-funded promos: LazMall and Amazon.sg brand storefronts co-fund category-specific promos that live inside brand pages, which is why brand-owned pages sometimes go deeper than sitewide codes. Third, timing: countdown drops release limited-stock vouchers at named hours (midnight, noon, 8pm) and burn quickly.

Use-case segmentation

• For the new-BTO-flat household basics buyer: plan around Lazada 9.9 for small appliances and Shopee 11.11 for bedroom textiles and cross-category top-up.
• For the fashion and beauty regular: Shopee 11.11 wins outright, with a smaller 12.12 top-up.
• For the US-brand tech loyalist (Kindle, Echo, Bose, CeraVe imports): Amazon Prime Day in July is the annual peak; a smaller Amazon Big Deal Days runs in October.
• For the price-first bargain hunter with no brand loyalty: track all three, cross-check on each platform on the day, and let the sitewide voucher stack decide.

When this does NOT apply

If you already have a specific SKU in mind and it is not a mass-market cross-marketplace item (say, a niche audiophile IEM or a Japanese-import cookware brand), the 9.9 / 11.11 / Prime Day tent-poles may not touch it. Also, high-ticket items like refrigerators and TVs often see steeper single-day drops during retailer-specific events (Courts Anniversary, Harvey Norman Superstore sale, Best Denki showcases) than during marketplace mega-sales. Check ShopBack for the current published cashback rate on each merchant page before spending, and cross-check the platform-native price against the retailer-owned promo before committing.

How to stack cashback on top

Use ShopBack to open Shopee, Lazada, and Amazon.sg from a tracked link so cashback attaches to the transaction. Activate the ShopBack Chrome extension or the ShopBack app before checkout so the click is registered inside the merchant window. Check ShopBack for the current published cashback rate on each merchant page before spending, because published rates change during mega-sale windows and per-category caps can apply. Cashback stacks on top of platform vouchers, credit-card promos, and bank-tie-up codes because it settles separately.

Frequently asked questions

When is Shopee 11.11 in Singapore in 2026?

Shopee 11.11 runs on November 11, 2026, with a pre-sale build-up window through the first 10 days of November and countdown deals opening at midnight on Day Zero. Historically the deepest sitewide vouchers appear in the first two hours after midnight and at named live-stream slots at noon, 8pm, and 11pm.

When is Lazada 9.9 in Singapore in 2026?

Lazada 9.9 falls on September 9, 2026, and typically runs a 24-hour Day Zero window with a preview period across the preceding week. LazMall brand storefronts (Samsung, Xiaomi, Dyson, Philips) usually publish preview lists two to five days before Day Zero.

When is Amazon Prime Day in Singapore in 2026?

Amazon Prime Day historically runs mid-July annually. Amazon has not confirmed 2026 dates at the time of writing, but the 2024 event ran two days in mid-July according to Amazon's newsroom, which noted "Prime Day 2024 was the biggest Prime Day event ever" (About Amazon, July 2024). Amazon.sg participates and requires a Prime membership.

Is Lazada 9.9 cheaper than Shopee 11.11 for the same item?

For LazMall consumer electronics and small kitchen appliances, Lazada 9.9 is often cheaper on Day Zero because the category is prioritised. For fashion, beauty, and cross-category general merchandise, Shopee 11.11 usually beats Lazada 9.9. Compare the specific SKU on both platforms on the day before deciding.

Is Amazon Prime Day worth the membership fee in Singapore?

For a shopper buying US-origin consumer tech (Kindle, Echo, Ring, Bose, Sony premium audio), one Prime Day basket can offset the annual membership cost several times over. If your basket is mostly Southeast Asian brands or fashion, 9.9 or 11.11 without a membership gate will serve you better.

What is the difference between 11.11, 12.12, and Black Friday in Singapore?

11.11 is the deepest sitewide voucher day on the Singapore marketplace calendar. 12.12 is a smaller top-up, typically two-thirds of the 11.11 depth. Black Friday in Singapore is dominated by US-brand and Amazon.sg promos, with more moderate participation from Shopee and Lazada. Adobe Analytics reported Cyber Week 2024 US online spend at "a record USD 41.1 billion" (Adobe, December 2024), which is the macro signal.

Can I stack ShopBack cashback with Shopee, Lazada, and Amazon vouchers on 11.11 or 9.9?

Yes. Cashback available on ShopBack settles separately from platform vouchers and bank-card codes, so all three layers can stack in principle. Activate ShopBack via the browser extension or the app before checkout so the click is tracked, and check ShopBack for the current published cashback rate on each merchant page before spending because category caps apply during mega-sale windows.

Which credit cards run the best 9.9 and 11.11 tie-ups in Singapore?

Historically DBS, UOB, Citi, and OCBC have run 9.9 and 11.11 tie-up promos with Shopee, Lazada, and Amazon.sg, offering incremental voucher codes on top of platform sitewide vouchers. Bank tie-ups change each year, so check the bank's own promo page before Day Zero. HSBC Revolution is a miles card, not cashback, and does not participate in cashback tie-ups.

What is the best time to shop on 11.11 in Singapore?

The first two hours after midnight and the 12pm and 8pm live-stream drops historically release the deepest sitewide vouchers. The 11pm final-hour push often unlocks a last sitewide code before the day closes.

How much do people spend during mega-sales globally?

Amazon's own newsroom described Prime Day 2024 as "the biggest Prime Day event ever" (About Amazon, July 2024). Adobe Analytics measured US Cyber Week 2024 at USD 41.1 billion, up 8.2% year on year (Adobe, December 2024). Singapore does not publish a dedicated 11.11 or 9.9 GMV figure, but the Department of Statistics Singapore records online sales at "an estimated 12.6% of the total retail sales value in July 2025" (SingStat, September 2025).

What categories are worth waiting for Amazon Prime Day vs buying at 9.9 or 11.11?

Wait for Prime Day if you are buying Amazon-owned devices (Kindle, Echo, Ring, Fire), premium US audio (Bose, Sony premium, Beats), and imported US-brand beauty and skincare. Buy at 9.9 or 11.11 if you are buying Southeast Asian brands, fashion, or general household merchandise.

Do I need to keep separate wishlists for 9.9, 11.11, and Prime Day?

Yes. The three events do not overlap on category strength, so a single wishlist rarely optimises across all three. Split by category: household small appliances into 9.9, fashion and beauty into 11.11, US-brand tech into Prime Day. Use ShopBack to compare rates across merchants inside each event window before committing.

Are 12.12 and Black Friday still worth it if I already shopped 11.11?

12.12 is worth it for follow-up top-ups and any Day-Zero-11.11 stock that was out. Black Friday in Singapore is worth it for US-brand tech and imported home appliances via Amazon.sg. Both are lighter than 11.11 in absolute voucher depth.

How do I track past prices to know if a mega-sale deal is really a discount?

Screenshot the SKU price two weeks before the event, again on the eve, and on Day Zero. Watch out for pre-event price mark-ups that make the Day Zero discount look bigger than the real net delta. Cross-check on the other two marketplaces at the same time. Check ShopBack for the current published cashback rate on each merchant page before spending as a final layer.

What is the difference between LazMall on Lazada and regular Lazada listings?

LazMall is Lazada's curated brand-authenticity storefront where listings come from brand-owned or brand-authorised sellers. LazMall SKUs typically qualify for LazMall-exclusive vouchers on 9.9 and 11.11 that regular listings do not. For electronics and beauty where authenticity matters, filter LazMall-only.
