9.9 Sale Singapore 2026: 8 Deals Worth Buying, Ranked by What You Actually Save

The biggest saving here in real dollars, and Nike's own navigation undersells it. The menu offers two rails, 'Up to 40% off' and 'Buy 2, Extra 20% Off', and they are not the same thing. The Up to 40% rail holds 1,586 products and its front page mixes 30%, 40% and 50% markdowns, so the 40% label is already wrong on the brand's own page. The Buy 2 rail is the one worth your time: 336 products, and every single item on it sits at exactly 50% off, with the extra 20% coming off in cart when you take two. That is a 60% effective discount, and it turns a pair of Air Force 1 '07 into S$119.20 against a usual S$298. Nike's own promotion record, tagged XAFA26NINEBUNDLE, dates the offer from 4 September to 2am on 11 September, so Thursday 10 September is the last full day to use it. One trap on the sale page itself: the Air Max Muse is listed twice, at S$114.50 and at S$137.40, and the only difference between the two entries is the colourway, so check both before adding to cart. Online at nike.com/sg, no code needed. We confirmed the Buy 2 rail was still live on 8 September 2026.

The deepest single number in this roundup, sitting behind the most misread condition. adidas prints EXTRA 30% OFF IN CART, not '30% off selected styles', and the badge only appears on stock that already carries a markdown. We checked 48 full-price men's shoes on adidas.com.sg and not one of them had it, which means the existing markdown is the number that decides your saving: on a 10% item the extra 30% lands you at 37% off, and on a 50% item it lands you at 65%. The richest corner is the Last Sizes rail, 152 products all at a flat 50%, where an Ultraboost 1.0 works out to about S$90.65 against a usual S$259. The catch is in the name, because last sizes means whatever is left, so the range is broad but your size may not be in it. The sale opened to adiClub members only on 1 September and to everyone from 2 September, and it runs to 10 September. adidas.com.sg was still serving a page titled '9.9 Sale: Extra 30% Off' on 8 September 2026.

The widest sale on this list and the one most likely to cover something you actually need, from bicycles to swim goggles. Decathlon's 9.9 Smashing Sale runs 5 to 10 September, and the banner across every page of decathlon.sg promises three things: up to 70% off, free delivery, and an extra $15 off with Atome. Two of the three are smaller than they look. The free delivery is a drop in the standard shipping threshold from $79.90 to $40, and standard shipping costs $2.90, so the perk is worth exactly $2.90 and only on baskets between $40 and $79.90. The $15 Atome voucher needs a spend of $129 or more, and Decathlon's own FAQ says the vouchers are strictly limited and first-come, first-served. The 70% is real but narrower than the banner suggests, because the asterisk reads products sold and shipped by Decathlon, which excludes partner brands such as Yonex, Molten and Manduka along with Second Life stock. Worth diarising: a flash-sale livestream at 8pm on 9 September. Worth knowing all year: the free 2-hour Click and Collect the banner counts as part of the offer is free with no minimum spend every single day.

The shortest fuse on this list, so if you want a pair, this is the one to do tonight. Crocs Singapore's 9.9 Flash Sale runs online at crocs.com.sg with 30% off almost everything plus doorbusters advertised at up to 50%, and checkout closes at 11.59pm on 9 September 2026. Prices are already cut on the product pages, so there is no code to enter. Read the rail properly, though, and the headline shrinks. Of the 41 items on the doorbuster page, only one is actually at the full 50%, the Bayaband Flip at S$27.48 from S$54.95, and when we opened it every women's size from 8 up was out of stock. The rest of that tier is 40%. The deepest cut on the whole site is not on the doorbuster rail at all: the InMotion LiteRide Micro Geo Clog in black is S$51.95 from S$104.95, which is 51%, and it is badged as an ordinary 30% item. The Classic Clog most people come for is S$52.46 from S$74.95. Bags and totes carry no discount, though a luggage tag does. Prices read off crocs.com.sg on 7 September 2026.

The best arithmetic lesson of this year's 9.9, and the reason to read a poster twice. LAC's 9.9 Mega Deals run on lac.sg to Thursday 10 September 2026, and the brand publishes the whole ladder in one line: Buy 1 Free 1 with $319 spend, then a $9 rebate at $299, $19 at $499, $39 at $699 and $99 at $999. Do the division and the rebate is the weakest thing on the poster. Nine dollars off $299 is 3.0%, and even the top tier only reaches 9.9%. The number that matters is $319. Stop at $299 and you take $9. Spend $20 more and a second copy of an item already in your basket comes free, which on LAC's $96.76 member-priced Probiotic Complex is $96.76 plus the $9 you still qualify for, or about a third off the basket. Two things the write-ups miss. Below $299 the 9.9 sale pays nothing at all, and the in-store version is worse than the online one: the brand's own poster prices the second same supplement at $9.90 in store, against free on the website. LAC's homepage was still carrying '9.9 Mega Deals: Instant Rebates Up to $99' and the code BF1TL on 8 September 2026.

The platform the whole date is named after, and the one where the discount depends on your reflexes rather than the product page. Shopee Singapore's site is fully 9.9-branded, and the campaign page at shopee.sg/m/99 leads on three things in its own words: a $99 Off $450 Flash Voucher, an extra 3% cashback for ShopeeVIP members, and same-day delivery on Fulfilled by Shopee orders through Buy Today, Get Today. Do the division on the headline voucher and it is 22% off, which is respectable for a platform-wide coupon and better than most of the coupon-aggregator codes floating around this week. The word doing the work, though, is 'flash': these are released in limited quantities at set times rather than sitting in your account all week, so the voucher tab in the app is where the sale actually happens. Two practical notes. Shopee prints no end date on the campaign page, so treat the tail end as uncertain. And the 3% ShopeeVIP cashback is a separate, stackable benefit on all orders, which is worth more than a single voucher if you are buying several things across the week rather than one big basket.

The clearest example this week of a promotion that loses to its own shipping charge. Sa Sa Singapore's 9.9 Beauty Specials run four days, Tuesday 8 to Friday 11 September 2026, and the whole campaign is two promo codes: $4 off a $50 spend with 99SAVE4, and $8 off an $80 spend with 99SAVE8. Two things worth getting right. First the channel: the ribbon printed under each coupon on Sa Sa's own artwork reads USE PROMO CODE ON MOBILE APP, not 'online', and when we searched sasa.sg we found neither code in the page source, no 9.9 banner on the homepage and no 9.9 entry on the retailer's own Promotions page. Second, and this decides whether the promotion is worth using at all: Sa Sa's Delivery Information page states a flat $10 delivery fee applicable to any order amount, parcel size or weight, with no free-shipping threshold at any spend. So $50 with 99SAVE4 costs $56 delivered and $80 with 99SAVE8 costs $82 delivered, and the shipping charge is larger than either coupon. One piece of arithmetic worth having: because $4 off $76 and $8 off $80 both land you at $72, every dollar you add between $76 and $80 is free. If this is your first Sa Sa order, the standing $5 new-member offer beats 99SAVE4 at every basket under $80.

The one to buy for Mid-Autumn rather than for yourself, and the only sale here that runs past next week. Bee Cheng Hiang's 9.9 sale went live on its web store on 1 September 2026 and it is online only, so none of it works at the counter. The brand's own campaign banner prints four things: 15% off Gourmet Fusion in 500g and 600g, 25% off the 1kg, Bakkwa Bites at $9.90 for 250g (a 39% cut off the usual $16.25), and a gift-with-purchase ladder at $80, $100 and $199 spend that pays out in mooncakes. Two details are worth more than the headline. First, the 250g Bakkwa Bites at $9.90 is cheaper than the 200g pack at $13.00, so the smaller size is now the expensive one. Second, the brand's own '9.9 Sales' page lists only eight products, while four more discounted lines sit in the ordinary Rolls and Snacks categories: three rolls at $9.90 against a usual $14.80, and Bakkwa Layer 90g at $19.90. There is a sting for anyone who bought in August, though. The Mala Crispy Pulled Pork Twist 200g that went for $10.92 in the National Day sale is $19.90 in this one. No closing date is published; the only date on the artwork is that delivery slots run to 24 September, the day before Mid-Autumn Festival.
