Does anyone know which are the best travel credit cards (no currency conversion charges) for UK residents?
Pick up a copy of Which? or Which? Money and check their tables.
Go to the Money Saving Expert website and see what Martin has to say.
Use Nationwide or Saga (if you are old enough) for good rates on Fx.
