Thanks for that. I've just checked again, I have no option to pay with points. I was trying to use them on the S23 pre-order.
I see you mention that you may not be able to use them, if an item already has an offer. So i tried to add a Galaxy Tag or Buds to test it but still no way of redeeming them.
My points don't have an expiry date near them either, could they be expired?
