2 live offers
Cashback sites pay you back a slice of what you spend at thousands of retailers — and nearly all of them add a welcome bonus on top when you join through a referral. That means free money before you've even earned your first cashback. The offers in this category typically require one qualifying purchase within a set window, so they're among the easiest bonuses on the site to unlock. We list the current sign-up rewards, minimum payout rules and how quickly each site actually pays out.
