I run an online web app which at the moment I charge for in GBP.  I'm expanding to the US and Europe and am looking for the best way to change the displayed price based on where the visitor is located.  Because I use PayPal, ideally it would be great if it took into account the fee PayPal charges for currency conversion, but if not it wouldn't be the end of the world.What would be the best way to do this do you think?
Changing displayed price based on visitor location?
