The most common question to PBR - "Why can't you list all your parts on a website and have a cart system like everyone else ?"
Simple - They have 100,000s of parts, and they would be spending all their time taking photos etc. Then they would not be able to process orders and speak to customers on the phone.
The International payment is a problem that is fairly easy to work with. I have credit at PBR - I go to the bank, write up a cheque for over US$1000 ish (whatever I have left over for parts). Costs me $30 to write the cheque, post it off to PBR and I can order without worrying about paying and invoice. With the US$ close to parity, there's no better time to order GTB parts etc. If you don't need anything, then the value is there once the dollar drops again.
