A post-purchase discount or rebate in Singapore is value that comes back after you pay, which lowers what the order really cost you. The three common kinds when shopping online are card rebates from your bank, platform coins such as Shopee Coins (100 Coins equal S$1, usable only in Shopee, per Shopee's Help Centre), and cash from ShopBack Singapore that you can withdraw. Each one arrives at a different time and in a different form.

ShopBack Singapore is a free app and website that returns part of what you spend at partner stores, such as Shopee and Lazada, as cash. Open ShopBack, tap the store, then check out. Join ShopBack Singapore for free so it is ready before your next order.

How do post-purchase discounts or rebates work when shopping online in Singapore?

You pay the normal checkout price, and part of it comes back afterwards from your bank, the marketplace or ShopBack. That is the difference from a voucher or promo code, which lowers the price before you pay. Both matter, because what you really spend is your effective price: the amount you paid, minus everything that comes back.

Here is the order things happen on a typical Shopee or Lazada order:

1. Before you pay: vouchers and coins you redeem lower the checkout total.
2. When you pay: your card is charged the checkout total.
3. After you pay: your bank works out the card rebate on the posted transaction, the marketplace may credit coins, and ShopBack records the order if you came through ShopBack.
4. Later: the card rebate appears on your statement, coins appear in your marketplace wallet, and ShopBack cash becomes withdrawable once the store confirms the order.

ShopBack lowers the effective price of flights, hotels and online orders after you pay, but the step itself comes before checkout: open ShopBack, tap the store, then check out.

What kinds of post-purchase rebates are there in Singapore?

The three kinds differ in who pays them, what form they take and where you can use them. Here is how they compare, based on published terms from Shopee and OCBC at the time of writing.

Type	Who gives it	Form	Where you can use it	Limits to know
Card rebate	Your bank	Credit on your card statement, or points or miles	Against your card bill, or in the bank's rewards catalogue	Monthly minimum spend and cap, eligible categories
Shopee Coins	Shopee	Coins, 100 Coins equal S$1	Inside the Shopee app only	Cannot be exchanged for cash, expire at the end of the third month
ShopBack	ShopBack Singapore	Cash	Withdraw from your ShopBack account	Order must be placed through ShopBack and confirmed by the store

Each one comes from a different place, so they are worked out separately on the same order. The amount and the timing vary by store, card and campaign.

How do credit card rebates work in Singapore?

Your bank returns a percentage of eligible spending, usually only once you reach a monthly minimum spend and only up to a monthly cap. OCBC's published terms for the OCBC 365 card are a clear example of how this works:

• OCBC counts the minimum spend on posted transactions in a calendar month.
• Below the S$800 minimum, OCBC pays a flat 0.25%.
• Before 1 November 2026, OCBC shows two tiers: S$800 minimum spend with an S$80 cap, and S$1,600 with an S$160 cap.
• From 1 November 2026, OCBC says the card moves to a single S$800 minimum spend and an S$160 monthly cap, with eligible dining, groceries and land transport at 6%, and telco, utilities, streaming and EV charging at the 0.25% base rate.

Other banks use their own categories, minimums and caps, and they change, so check your card's current terms. The key point for online shopping is that a card rebate depends on what category your bank puts the purchase in and how much you have already spent that month.

How do Shopee Coins and ShopeeVIP work after you pay?

Shopee Coins are Shopee's own reward points: 100 Coins equal S$1 off your next purchase in the Shopee app, according to Shopee's Help Centre. You earn Coins from purchases, activities and tasks in the app, then switch on Redeem Shopee Coins at checkout to use them. Shopee says Coins cannot be exchanged for cash and expire at the end of the third month from when they were earned, counting the month you earned them as the first month.

ShopeeVIP is Shopee's paid membership. Shopee lists it at S$3.99 a month, S$20.94 for six months or S$29.88 for twelve months, with Coins back on orders capped at 1,000 Coins per order and 6,000 Coins per month, plus 400 Coins a month and free doorstep delivery with no minimum spend on items Fulfilled by Shopee.

Because Coins can only be spent inside Shopee and they expire, they behave like a voucher for your next Shopee order rather than money in your pocket.

What about Lazada?

Lazada runs its own vouchers and in-app rewards, and lists the terms for each in the Lazada app. Lazada was founded in 2012 and is owned by Alibaba Group. Its vouchers are applied before you pay, so they lower the checkout total; post-purchase value on a Lazada order then comes from your card rebate and from ShopBack if you open Lazada from ShopBack before checking out.

How does cashback work in Singapore?

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. With ShopBack Singapore, the steps are short:

1. Open ShopBack on the app or at shopback.sg.
2. Tap the store, for example Shopee on ShopBack or Lazada on ShopBack. The store opens from ShopBack.
3. Check out as usual in the same session, with your vouchers and your usual card.
4. Watch it arrive. The order shows in your ShopBack account, and once the store confirms it, the cash can be withdrawn.

Open ShopBack, tap the store, then check out. That order matters: if you go straight to the store app, ShopBack usually cannot track the order. Some promo codes or payment methods can affect tracking, so read the terms on the store's ShopBack page before you pay.

How does cashback work on Shopee vs Lazada?

It works the same way on both: open ShopBack, tap the store, then check out, and the rate shown on each store's ShopBack page applies. Rates differ between stores and change by campaign, so compare the live rates rather than a figure you remember.

To compare the same item across the two stores:

1. Put the item in your cart on Shopee and on Lazada.
2. Apply the best vouchers each store offers you, and note the shipping cost.
3. Note the final amount that will be charged to your card.
4. Check the live rate on Shopee on ShopBack and Lazada on ShopBack.
5. Work out the effective price for each, and buy where it is lower, going through ShopBack first.

How do I spot the best deals in Singapore in 2026 with post-purchase discounts?

Judge a deal by its effective price, not its sticker price. A product that looks cheaper on one store may end up costing more once vouchers, shipping and what comes back are counted.

A worked example, using illustrative numbers. Say an item is S$155 after vouchers, and you redeem 500 Shopee Coins at checkout.

• The 500 Coins take S$5 off before you pay, per Shopee's 100 Coins to S$1 value, so S$150 is charged to your card.
• At an illustrative 4% rate through ShopBack, S$6 comes back as cash, so the effective price is S$144.
• Your card rebate is worked out separately by your bank on the S$150 charge.

The 4% rate is only an example. Check the live rate on the store's ShopBack page, since it changes by store and campaign. Big sale days such as 11.11 (Wednesday 11 November 2026) and 12.12 (Saturday 12 December 2026) are when this comparison is most useful, because voucher and rate changes are frequent.

What should I watch out for with post-purchase discounts?

The main things to watch are timing, returns and expiry.

• Timing: post-purchase value arrives later, not at checkout. Card rebates follow your bank's statement cycle, and ShopBack cash becomes withdrawable once the store confirms the order.
• Returns: if you cancel or return an order, the amount due to come back is usually reduced or removed. Card rebates are usually adjusted too.
• Expiry: Shopee Coins expire at the end of the third month, per Shopee. Use the oldest Coins first.
• Session: for ShopBack, finish the order in the same session after tapping through.

Other stores where this applies

The same approach works beyond Shopee and Lazada: Amazon.sg, Taobao, Zalora and Agoda also have store pages on ShopBack Singapore, so you can open ShopBack, tap the store, then check out.
