Coupert, a free browser extension and mobile app, generated $28.49 in cashback and coupon savings for one user during their first week of testing. The platform works across 200,000+ online retailers and automatically applies available discount codes at checkout while tracking cashback offers.

Here's how it functions. When you shop online, Coupert's tool searches for applicable coupons and cashback deals without requiring manual effort. You can cash out earnings through PayPal, gift cards, or direct debit card transfer. The minimum withdrawal threshold sits at just $1, meaning you can access funds quickly.

The service costs nothing upfront. A paid upgrade exists for users who want additional features, but the base version handles coupon hunting and cashback tracking at no charge.

Dollar Sprout's reviewer achieved nearly $30 in savings during week one, though results vary depending on shopping volume and eligible purchases. Regular online shoppers, particularly those buying from major retailers, stand to benefit most. Someone purchasing groceries, clothing, electronics, or home goods through partner merchants could accumulate savings faster.

The real value proposition targets people who already shop online frequently but don't manually hunt for codes. Instead of visiting coupon websites or remembering promotions, Coupert handles the legwork automatically. The tool essentially turns routine shopping into a passive earning activity, provided the extra discount codes actually apply to what you buy.

One limitation worth noting: savings depend entirely on participating retailers offering cashback through Coupert's network. You won't earn rewards on every purchase. Additionally, some users report mixed results with code application across different sites.

For casual online shoppers, $28 weekly represents modest savings. That translates to roughly $120 monthly or $1,440 annually if earnings stay consistent. More serious shoppers could potentially exceed these numbers. The low barrier to entry—free to download, minimal effort required
