Jfc 70 american bucks are barely 62€, I've just noticed this and I end up losing money cause the dollar has kind of little value overseas. Not blaming anyone but capitalism here.
if your CC (or the client's CC) has a better exchange rate, you can iirc force PayPal to use the CC's exchange rate instead by sending the money in the original currency (e.g. have the client send 62€ instead of $70USD)
