Thanks for your reply.
I have read this article before. I’m using “option 2”, that is, I have a base shipping cost plus a charge per item. That bit works well.
However the shipping cost is for domestic orders only. I cannot offer shipping outside Australia (my country), so I need to prevent international shipping.
Unfortunatly the Australian version of Paypal does not offer the ability to turn off international shipping. Paypal said I need to do it through my website.
Regards,
Tony
