Which SG deals are actually working this month, not just listed somewhere? Dealy editors re-verify every entry below every Friday from a SG IP. Our SG editor re-verifies every deal in this list every Friday from a SG IP. Thirty-plus working SG deals this month, organised by category and tagged with the actual saving in S$ before you commit.

Travel
The travel category is where May saving hits the hardest. School-holiday demand is up but supply has expanded faster, so card-microsite discounts are deeper than CNY.
HSBC Revolution + Trip.com hotels: S$150 off, min. S$500, Wednesdays only. Largest absolute saving this month.
Citi Mastercard + Trip.com flights: Up to 50% off, cap S$50, Fridays at noon. Quota burns in under an hour.
Mastercard World Elite + Agoda: 16% off all coupon-eligible rooms, cap S$60 per booking, auto-applied.
DBS Live Fresh + Klook: S$10 off code with min. S$150 cart. 200-redemption daily cap, book before 11am.
YouTrip + Klook Wednesdays: S$40 off select attractions. App-only, capped at 200 redemptions per day.
HSBC + Klook hotels: S$150 off, min. S$500, Wednesday drops.
For the full breakdown, see the Trip.com Singapore shop page for live codes and our Trip.com Singapore guide. For Agoda card stacking, the Agoda card discount guide ranks every SG bank. For Klook, the Klook stacking guide covers the full card table.
Ecommerce
Shopee 5.5 ran through 5 May and the platform voucher S$15 off is still valid for the rest of May on a minimum S$120 cart. Lazada's mid-month drop arrives on 15 May with a SuperSeller voucher matching the Shopee saving.
Shopee S$15 off voucher (min. S$120): valid until 31 May. Stack with seller voucher and Citi Cash Back 8% rebate.
Lazada SuperSeller voucher (min. S$150): drops 15 May, runs to 25 May. UOB EVOL 8% online stacks on top.
iHerb NEW20: 20% off first order, valid year-round, but stack with the May 11.11-equivalent mid-year promo for another 10% on most brands.
SAFRA Shopee S$15 off: SAFRA-only code listed in SAFRA Members app under Lifestyle Perks. Min. S$120 spend.
The Shopee voucher stacking guide covers the platform-voucher-first rule that keeps the S$15 from disappearing on you.
Supplements and health
iHerb has the deepest catalogue, but watch the S$60 free shipping threshold.
iHerb NEW20: 20% off first order, codes work on most categories except Now Foods (10% cap) and clearance. Live codes on the iHerb Singapore shop page.
Watsons + ShopBack: 5% rebate on full-price items. Useful when iHerb shipping speed is too slow.
Guardian + DBS PayLah!: S$5 off S$50 spend, in-store only, valid until 31 May.
Full price-comparison math against Watsons sits in the iHerb Singapore shipping cost guide.
Groceries
Grocery deals run through the major chains' loyalty programs more than promo codes.
FairPrice + OCBC FRANK: 11% off online groceries above S$80, cap S$25 a month.
Cold Storage + Citi PremierMiles: 4 mpd on supermarket spend, no cap.
Giant + UOB One: 5% rebate, cap S$50 quarterly with the S$500 minimum quarterly spend requirement.
RedMart + Lazada vouchers: 10% off baby and household categories during the mid-month drop.
Streaming and software
Smaller category but two stand-out plays:
Disney+ annual prepaid: S$118.98 for 12 months, equivalent to ~S$9.92 a month vs the S$12.98 monthly rate. Auto-renews.
Norton 360 Standard: 60% off year one, S$31.99 for 12 months (was S$79.99). Valid until 31 May.
fiverr Pro membership: 25% off first three months, valid for SG accounts created in May.
Local services
Domino's Mondays: 50% off pickup orders, S$10 minimum, every Monday throughout May.
AirAsia SG to KL: From S$45 one-way, sale ends 28 May.
Circles.Life portable plan: First month S$10 for 100GB, valid for new SG numbers in May.
What changed since April 2026
Three things shifted this month worth knowing:
Mastercard World Elite cap reduced from S$70 to S$60 on Agoda from 1 May. The 16% headline rate is unchanged.
HSBC Revolution Card added a S$150 off Trip.com hotel tier above S$500, replacing the older S$80 off above S$300. Net better for bigger bookings, worse for smaller ones.
Shopee moved 5.5 platform vouchers to longer validity (full month) but tightened minimum spend from S$100 to S$120. Below S$120 carts, you now stack seller voucher only.
How do we actually test these deals?
Every code is tested at checkout on a Singapore IP between 2026-05-04 and 2026-05-11. We log in with a fresh account when needed, complete the cart through to the payment screen, and verify the final price matches the headline saving before backing out. Codes that fail at the payment screen are removed from the roundup the same day.
