Cash back shopping portals are the lowest-friction sign-up bonuses on this list. Most ask nothing more than creating a free account or installing a browser extension — and in exchange you get a welcome bonus plus ongoing cash back on purchases you were going to make anyway.
I’ve been using cash back portals for over a decade and manage accounts across most of the major platforms. The ones below are the ones I actually recommend — not just anything with an affiliate program. If it’s on this list, I’ve personally used it or verified it’s worth your time.
As with everything on Refer for Good, every commission I earn from your sign-up goes directly into Kiva.org microloans for entrepreneurs in developing countries. Learn more about our impact →
Capital One Shopping — $80 bonus ⭐ Top pick
Why it’s #1: No purchase required. This is rare — most cash back portals require you to spend money to unlock the welcome bonus. Capital One Shopping just needs you to install the free extension and use it for 90 days. Works at 100,000+ stores. Completely free.

Rakuten — $50 when you spend $50
Why it’s worth it: The most widely used cash back portal for a reason. The browser extension activates automatically when you shop at 3,500+ stores — no remembering to click through. Pays out quarterly via PayPal or check. The $50 welcome bonus lands after your first qualifying $50 in purchases.

TopCashBack — $15 cash back
Why it’s worth it: Frequently beats Rakuten on rates at specific retailers. Good to have both installed — the extensions don’t conflict. Earn $15 when you join and complete your first cash back transaction.

Extrabux — $20 cash bonus
Why it’s worth it: $20 just for joining, plus solid rates at 5,000+ stores. Built-in coupon stacking on top of cash back is genuinely useful.

Mr. Rebates — Up to $5 sign-up bonus
Why it’s worth it: I’ve personally used this for over ten years. Solid rates, reliable payouts. Worth having alongside Rakuten and TopCashBack since rates vary by retailer.

💡 Pro tip: Stack multiple portals for maximum return. Install Rakuten, TopCashBack, and Capital One Shopping simultaneously — the extensions don’t conflict, and you can activate whichever offers the highest rate for a given store. This is how experienced cash back users maximize returns on every purchase.
