I can't be bothered with ukash, is bank wire just sending money straight from my bank online like I did with Mt.Gox until they shut that down on the 25th?
Yes, except for the shutting down part.
Is the problem, whatever it is, not on Barclays end? That's what Mt.Gox is saying, how come it will work with your site and not anothers, amount of traffic or something?
