Cashback vs Card Rewards: Which Should You Use?
A cashback platform and a rewards credit card are not alternatives. They live at different layers of the same transaction and are funded by different parties, so they stack on the same purchase. Use the cashback platform as your default for online retail, and use a rewards card for everything else (with cashback layered on top whenever both apply).
Overview
Use both. They stack.
A cashback platform and a rewards credit card sit at different layers of the same purchase and are funded by different parties, so they never compete for the same dollar. The cashback platform pays you a share of the retailer's affiliate commission for sending you to the store. The card pays you a share of the issuer's interchange revenue for swiping the card. Both can apply to the exact same checkout, and combining them is the highest-return way to pay for most online purchases.
Key facts
- Different funders. The cashback platform is paid by the retailer's affiliate budget. Card rewards are paid by the card issuer out of interchange fees. Neither one cancels the other.
- Both can apply on the same purchase. Click through the cashback platform, pay with your rewards card, earn at both layers.
- The cashback platform is online-only and applies at participating retailers. Card rewards apply anywhere the card is accepted, online or offline.
- Typical earn rates: 1 to 10 percent at the cashback layer (varies by retailer and category), and 1 to 5 percent at the card layer (varies by card and category).
- Combined return on a stacked online purchase is often 4 to 10 percent, sometimes more during promotions.

When the cashback platform leads
- Online retail at a participating store. Affiliate-funded cashback is set per retailer and is often several times the card's base rate, so it does the heavy lifting on the trip.
- High-cashback categories. Travel bookings, electronics, fashion, and beauty often carry boosted cashback rates that outrun typical card multipliers.
- You want flexible cash you can withdraw. Approved cashback is real money you can move to your bank account; many card programmes pay in points or statement credit instead.
When the card leads
- Offline purchases. Groceries at the supermarket, food at a restaurant, fuel at the pump. The cashback platform can't reach the transaction, so the card is the only rewards layer running.
- Non-participating retailers. If the online store isn't in the cashback network, the card still earns at its base rate.
- Recurring bills and subscriptions. Utilities, mobile plans, insurance, and streaming services typically don't sit in affiliate networks. Routing them through a rewards card keeps a small return on otherwise zero-reward spend.
- Everyday spend across categories. The card is the always-on baseline. It catches everything the cashback platform can't.
Worked example
A SGD 200 online purchase at a participating retailer.
- Card alone (1.5 percent base rate): SGD 3 in card rewards on the next statement.
- Cashback platform alone (5 percent on this retailer): SGD 10 cash, paid after the return window.
- Both stacked: Click through the cashback platform, pay with the same rewards card. Earn SGD 10 cashback AND SGD 3 in card rewards on the same transaction. Combined: SGD 13, or 6.5 percent of the purchase.
The stack happens automatically once the click-through and the card swipe both fire. There's nothing to claim, nothing to coordinate. Values are illustrative.
How to start
Sign up for ShopBack as your default cashback layer for online retail, and use any rewards credit card you already hold (or plan to apply for) as the card layer. When you buy online at a participating store, click through the cashback platform first and pay with the rewards card. For everything else (offline shops, bills, non-participating retailers), the card runs on its own and still earns.
FAQs
Do I have to choose between cashback and card rewards?
No. They are paid by different parties and sit at different layers of the same purchase, so they stack. The cashback platform earns the retailer's affiliate commission share. The card earns the issuer's interchange share. Both can land on one transaction.
Which one earns more on a typical purchase?
On a participating online retailer, the cashback platform is usually the larger layer (often 3 to 10 percent versus 1 to 5 percent for the card). On offline or non-participating spend, the card is the only layer running. The right question isn't which earns more, it's whether both are active when they can be.
Can both apply if I pay with my rewards card and click through ShopBack?
Yes. The cashback platform tracks the click-through and the retailer pays out at the affiliate layer. The card tracks the swipe and the issuer pays out at the interchange layer. They run on separate systems and don't interfere.
Do I need a specific card to stack with the cashback platform?
No. Any card that earns rewards (cashback, points, or miles) will stack, because the card layer is independent of the cashback platform. Pick the card on its own merits (earn rate, fees, perks). The cashback layer sits on top regardless.
Does the cashback platform replace the need for a rewards card?
No. The cashback platform only covers online retail at participating stores. A rewards card covers the rest of your spending (offline, bills, non-participating retailers) and still adds a second layer on top of cashback when both apply. The two together cover almost every transaction; either one alone leaves money on the table.
