OG turned 64, and its anniversary sale opened today, Thursday 27 August 2026. It runs to Saturday 4 October 2026, which is close to six weeks.
> Quick view: 27 Aug to 4 Oct 2026 · OG Albert (60 Albert Street) and OG People's Park (100 Upper Cross Street), 11am to 8.30pm daily · 20% off storewide in store, plus Rewards Points redemption and free gifts with purchase while stocks last · the real lobang is not the 20%: this is the only window all year where a Basic member upgrades to OG Gold on a $75 nett same-day spend instead of $300.
The headline number, and where it applies
OG's own campaign artwork reads "Unlock OG Anniversary Deals, from 27 Aug till 4 Oct 2026", with three pillars printed across it: Storewide 20% OFF, Rewards Points Redemption and Free Gifts with Purchase. The 20% is the in-store markdown, and OG has exactly two stores left:
| Store | Address | Phone |
|---|---|---|
| OG Albert | 60 Albert Street, Singapore 189969 | 6210 2222 |
| OG People's Park | 100 Upper Cross Street, Singapore 058360 | 6535 8888 |
Both open 11am to 8.30pm, Monday to Sunday, per OG's own site.
One qualification is worth carrying with you. The 20% is a markdown on regular-priced items, not on everything with a price tag. Lines already carrying a reduction, and OG's grey-tag and red-tag clearance stock, sit outside that language; OG's own membership terms name those same tags as exclusions elsewhere. Confirm at the counter before you assume.
The number actually worth planning around: $75 against $300
OG's membership FAQ is unusually blunt about this. To upgrade from Basic to Gold:
- During the OG Anniversary Sale: $75 nett, same day, at any OG store.
- After the OG Anniversary Sale: $300 nett, same day.
That is a 4x difference on the same upgrade, and OG's membership page explains why the calendar lines up: Gold renewal "runs in conjunction with the OG Anniversary Sale", which it says "typically starts on the last Thursday of August each year". 27 August 2026 is the last Thursday of August.
Four conditions decide whether your spend counts:
- Register as a Basic member before you pay. OG's FAQ says purchases made before you registered cannot be used to upgrade. Basic is free, has no minimum spend and no expiry, so do it on the way there at og.sg/ogmp or through the OG Member's Portal.
- Quote your mobile number or email at the cashier, on every receipt you want counted.
- You may combine receipts, as long as they are all from the same day.
- OG Rewards redemption items and OG Shopping Vouchers do not count towards the $75.
What Gold buys you: a 10% rebate on non-discounted merchandise, held as stored value you spend on a later OG purchase inside the membership year; 1 rewards point per $10 spent; Gold-only promotions; and invitations to sale previews. Gold runs to 30 September of the following year, with rewards points redeemable up to 31 October.
Read the rebate clause carefully, because it cuts against the sale itself. OG states the 10% rebate is not given in conjunction with other promotions, nor on grey-tag and red-tag items, rewards redemption items or OG Shopping Vouchers. In plain terms, you are unlikely to bank 20% off and a 10% rebate on the same item. Treat the $75 as buying next year's rebate cheaply, not as a stack you enjoy today.
Online is a separate sale, and on most lines a much better one
OG's website runs its own OG 64th Anniversary collection, and it is not the same 20%. Fourteen lines were listed on 27 August, all in stock, and eight of them beat the in-store markdown outright:
| Item | Anniversary price | U.P. | Off |
|---|---|---|---|
| EGMONT Manuka Honey UMF12+ 1kg, bundle of 3 | $225 | $675 | 67% |
| Ocean Health Omega-3 Fish Oil 1000mg 250s, twin pack | $79.90 | $222.50 | 64% |
| Odette Riviera stand mixer / hand mixer, grey | $64 | $149.90 | 57% |
| Oxford Project sling bag, blue | $29 | $59.90 | 52% |
| COMVITA JKJ Red Ginseng Manuka Honey Drink 30 x 15g, bundle of 2 | $125 | $250 | 50% |
| SHISEIDO Ultimune Iconic Glow Set | $238 | $460 | 48% |
| SHISEIDO Vital Perfection Intensive Sculpting Set | $365 | $660 | 45% |

| Lancome Renergie Collagen Lift-Xtend Cream 50ml + 3-pc gift | $145 | $207 | 30% |
| Lancome Genifique Repair Shot 20ml Set | $116 | $165 | 30% |
| GoodMorning G Sure + V Protein 850g | $75.80 | $84.20 | 10% |
Delivery runs from $2.99, free on online orders of $200 and above, per the notice OG carries across its own site.
Two stacking windows, and they close this weekend
OG's site carries two brand days on top of the anniversary sale. Both are online, and both apply the discount automatically at checkout:
- LANCOME Super Brand Day: an additional 20% off regular-priced products, 28 to 30 August 2026.
- SHISEIDO Tea Party: an additional 20% off regular-priced products, 28 and 29 August 2026.
Note the words *regular-priced*. The already-reduced anniversary sets in the table above are not regular-priced, so do not expect the extra 20% to land on them. The stack is for the full-price Lancome and Shiseido lines.
Separately, OG is running an online-exclusive Skater Hello Kitty purchase-with-purchase: a $50 nett same-day online purchase lets you buy the 540ml Hello Kitty Thermal Food Carrier at $39 (U.P. $62) or the 300ml at $29 (U.P. $48), while stocks last. The minimum spend excludes the delivery fee.
Paying with NETS shaves another 1%
OG published NETS terms for the anniversary period. Pay in a single NETS transaction of $100 or more at a manned cashier counter at OG Albert or OG People's Park and you get 1% off the total bill, GST included, as a direct discount.
The fine print is where it gets fiddly:
- Qualifying cards are NETS ATM and debit cards issued by DBS/POSB, HSBC, OCBC, Maybank, Standard Chartered and UOB, plus NETS FlashPay, NETS Motoring and NETS Prepaid cards.
- Qualifying QR apps are the NETS app, DBS PayLah!, DBS and POSB digibank, OCBC, UOB TMRW and Maybank2u SG, along with eligible LifeSG users.
- Apple Pay, Google Pay and Samsung Pay are excluded, even where the underlying card would qualify.
- Full payment only. Deposits and partial payments do not count.
- Not valid online, and not at self-service kiosks.
- Not given on rewards redemption items or OG Shopping Vouchers.
How to play it
- Register for Basic membership before you leave the house. It is free, it takes a minute, and signing up at the counter after you have paid does not rescue the receipt.
- Decide first whether you want the $75 gate or the online prices. The Gold upgrade needs an in-store spend. The deepest markdowns are online.
- Go on a weekday if you can. Six weeks is a long runway, but free gifts are while stocks last, and those go early.
- Do not manufacture spending to reach $75. If you were not going to buy $75 of anything, a rebate you can only spend at OG next year is not a saving.
- This weekend is the Lancome and Shiseido window, 28 to 30 August and 28 to 29 August respectively, and it does not come round again inside this campaign.
