USA: Rakuten (best overall, $30 signup bonus), Ibotta (best for groceries). UK: TopCashback (highest rates), Quidco (great welcome offers). Australia: ShopBack (best coverage), Cashrewards (strong Woolworths/Coles partners). Sign up to all — they cover different retailers and stacking cashback with coupon codes is allowed on most platforms.
Cashback sites earn a referral fee from retailers when you click through their platform and buy — then share a portion of that fee with you as cashback. It’s genuinely free money, and the rates have improved as competition between platforms has intensified. The average UK cashback user saves £150–£300 per year; US users average $100–$200 depending on spend categories.
Best Cashback Apps — USA
Rakuten — Best Overall USA Cashback App
Rakuten covers 3,500+ US retailers with cashback rates of 1–15% depending on the store and promotion period. New members typically receive a $30 welcome bonus after their first qualifying purchase. The quarterly payout structure (via PayPal or check) is reliable. Rakuten’s browser extension triggers automatically on supported retailer sites, making activation effortless.
Best rates on: Walmart, Target, Nike, Macy’s, and hotel/travel bookings. Cashback stacks with coupon codes in most cases.
Ibotta — Best for Grocery Cashback USA
Ibotta specializes in grocery and everyday shopping cashback. Link your store loyalty cards (Kroger, Walmart, Target) and earn cashback automatically when you buy qualifying items. The app shows available offers before you shop so you can plan purchases around cashback opportunities. For families and regular grocery shoppers, Ibotta consistently outperforms generic cashback platforms on everyday items.
Best Cashback Sites — UK
TopCashback — Highest Rates in the UK
TopCashback consistently offers the highest cashback rates among UK platforms — they pass nearly all the retailer commission to the user, making their margin on the free tier extremely thin. This means you’ll often see TopCashback offering 6–8% where Quidco offers 4–5% on the same retailer. For high-value purchases (insurance, broadband, travel), the difference can be significant.
Works across 5,000+ UK retailers. Browser extension available for Chrome/Firefox. Payout via PayPal, bank transfer, or gift cards (bonus rates on gift card payouts).
Quidco — Best Welcome Bonus UK
Quidco is the UK’s other major cashback platform. Rates are slightly lower than TopCashback on average, but Quidco often runs promotional cashback periods with enhanced rates that exceed TopCashback temporarily. Register with both and check both before every purchase — the site with the higher rate will differ by retailer and time. Quidco’s mobile app is generally considered more polished than TopCashback’s.
Best Cashback App — Australia
ShopBack — Best Overall Australia
ShopBack is the dominant cashback platform in Australia with 1,200+ retailer partners including Woolworths, JB Hi-Fi, Booking.com, Agoda, and most major Australian e-commerce sites. New members receive a welcome bonus after their first qualifying purchase. The app includes a “Cashback Hero” deal section highlighting the highest current cashback rates by retailer. Available on iOS and Android.
Frequently Asked Questions
Can you use cashback and coupon codes together?
Usually yes — most cashback platforms allow you to stack a coupon code with cashback on the same purchase. The exception is certain promotional cashback periods where the retailer restricts code use. Check the specific retailer’s terms on the cashback site before applying both.
How long does cashback take to pay out?
Most cashback needs to go through a “pending” period (typically 30–90 days) while the retailer confirms no returns were made. Once confirmed, it moves to your cashback balance for withdrawal. Rakuten pays quarterly. TopCashback and Quidco allow withdrawal once you reach a minimum threshold (usually £1 or £5).
Final Thoughts: Register for your country’s top two cashback platforms, install their browser extensions, and check both before every online purchase. The minutes spent comparing rates pay dividends on any purchase over $50. For UK shoppers especially, TopCashback + Quidco together cover essentially all major retailers at consistently strong rates.
