Gutted you dont have any amazon GBP cards

Concur.
I've still got a pile of Noblecoins and was watching how this develops. The focus on US market is a shame. UK pound and the Euro would be great. Hopefully it will happen soon. The bigger the market, the bigger the demand = noblecoin price will soar pass the moon.
With coinpayments supporting multiple currencies as well as the e-commerce backend we do intend to push support internationally. Whether we do that with other merchants in their region buying/supplying (trust is always an issue in this scene) or develop it ourselves is still to be decided.
