Curve Card: Spending Curve Reward Points?

jet01

You could get them to ring through the exact amount you have available as a card payment at the till in a shop/supermarket and then pay the remaining amount with cash or reward points. I got them to just charge the exact amount I had left on there to the curve card so I wasn’t left with any balance and then paid for the rest of my shop using the balance from my co-op card. Obviously won’t ,t work at a self service till as the card would be just rejected.
