Thanks Riddar,
I think I get charged about £22 for a bank wire from my bank, which tips the decision somewhat.
So once verified and the wire has gone through, how much do OKpay take off the top? The site suggests £4 but the wording is a little vague.
£26 and a few days wait almost makes it not worth it, considering the "get quickly" services such as BitBargain then come close to the overheads.
