Just to let you know, if you pay with Paypal but use your credit card as the funding source CBA will still charge you an international transaction fee if the merchant is overseas. I noticed this when I bought a humble bundle recently, I paid in AUD through Paypal but used my CC as the funding source and got charged an international transaction fee from CBA because the merchant/store (in this case humble bundle) isn't based in Australia. So if you're going to pay via Paypal have the funding source as your actual bank account instead or you'll still pay fees
