We’re different from other referral sites: we don’t keep the commission — every dollar earned through these links funds Kiva microloans for entrepreneurs around the world. [Advertiser Disclosure]
Last updated: October 2026
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 →

This is how experienced cash back users maximize returns on every purchase.
