Today, Curve launches their newly revamped Curve Cash program, where premium users can get 1% extra cashback on a range of retailers from the EU and beyond for an unlimted time. Free users still get the same offer for their first three months as members.
| Curve Blue | Curve Black | Curve Metal |
|---|---|---|
| 1% Instant Curve Cash for 90 days | 1% Instant Curve Cash for unlimited time | 1% Instant Curve Cash for unlimited time |
| Choice of up to 3 retailers | Choice of up to 3 retailers | Choice of up to 6 retailers |
This cashback comes in addition to whatever miles or cashback you’re earning on the underlying card.
Example: I use my Chase Sapphire Reserve (which earns 4.5% cashback on travel purchases and dining out) as the underlying card when paying with Curve at e.g. Booking.com, Uber, Foodora, or Starbucks. Now I earn a total of 4.5% + 1% = 5.5% on the purchase. 
You can spend the cashback instantly at any retailer that accepts Mastercard (including topping up your Revolut balance).
Note 1: Currently you can’t change the retailers you have selected, but Curve is considering implementing that in a future update.
Note 2: The new Curve Cash program is not available to “Legacy Black” users, meaning those who paid a one-time fee for Curve Black in the past and haven’t upgraded to the new Black plan.
I’ve updated my Curve article to reflect the new changes:
Remember that you get £5 in Curve Cash by using the code NOMAD when signing up for Curve.
