In reply to Andy Cloquet:
I have a Paypal cash card, linked to my Paypal account, costs nothing for the money to go in (well, in theory, items I sell on my website lose about 2%, but then again Paypal allows people to use their credit cards to buy from me over the internet). As far as I know I can load it form my bank account for free as well, but I haven't done this for over a year.
Cash withdrawal fees are pretty much the same as for my debit card.
However like so much in life big business has tried to make things as confusing as possible. What we need is a system where currency & cash card businesses have to all use the same fixed (daily) exchange rate, then put a single clear commission percentage on top, so that us consumers can compare like with like.
