1% cashback
Curve
Sign up for a free Curve Mastercard through my referral and execute a first payment with your card, upon which you'll enjoy 1% cashback on your purchases for 30 days. Curve allows you to roll all your Visa & Mastercard cards into one, so you'll never have to leave the house with a stuffed wallet again. Simply select and switch the underlying card in the Curve app on-the-fly. Use the Go Back In Time feature to move payments over to another card up to 30 days after the fact. You can also select up to 2 fallback cards so you'll never have to face refused payments at the register again.
