Receive 10% cashback when you buy $50 DoorDash gift cards on Cashrewards. All other denominations will earn the standard rate of 3% so make sure you only buy the $50 DoorDash gift cards.
If you can’t access the DoorDash gift cards that are 20% off at Costco, 10% cashback isn’t a bad consolation prize. At the time of writing, ShopBack are also offering 10% cashback on DoorDash gift cards.
