Much cheaper than transferring money through the bank (as far as I can see) and all done very efficiently.
Review by confirmed purchaser
It's a bit scary transferring money out of your account through an internet company who you don't really have any tangible hold on; but in the end, you have to trust someone. I did everything online, though I did phone the office once for one clarification.which was a good experience. The e-paperwork was also very good - better than I was expecting.
