Can anyone suggest a way of dealing with variable postage rates in PayPal. I will need to deliver to US, Australia, Hong Kong etc as well as the UK. I would rather not set a very high rate for all which would penalise those in the UK. The rate will vary between £1.50 and £4.50. per item. I could add text to cover each region but how would that be incorporated into the PayPal invoice?

I don't seem to have any luck here. I will talk to pPayPal about splitting the cost at some stage to reflect differential shipping costs. Has anybody else come across this?

I'm not an "expert" with PayPal; but have recently set up the "add to cart" buttons for my site. (Using the button creator at PayPal site)
There are options that allow you to specify many different regions, by name, and assign a shipping rate to them.
You will have to use the PayPal site to create the buttons, then just copy/paste into an html box on your pages.
