TopCashback is currently running a redemption promotion: cashing out for gift cards like Nike, Sephora, Target, and Gap gets you an extra 10% bonus.
Redeeming for Virtual VGC gets a 5% bonus, physical AMEX gift cards get 3%, and Amazon gets 2%. Just a reminder: Virtual VGC and AMEX gift cards can be directly added to Amazon to buy gift cards, so there’s no real need to redeem for Amazon.
