I use PayPal as one of the online payment gateways to process online transactions. At work today, we were discussing the additional International / Cross Border fees credit card companies like Visa started charging about a year or two ago. As there are several pages one could read to find out how much PayPal charges when accepting payments from another Country, I kept looking around the web to see if it was outlined in greater detail.
For example, how much does PayPal charge when I (Canadian account) receive payments from a US Customer (US Credit Card/Account)?
