We have 3 shipping categories:
Canada
USA
International
Since we ship almost 100% by
Lettermail
Light Packet
Small Packet
shipping is real easy to set up. Every item, depending on thickness/weight is assigned a shipping category.
We only charge shipping for one item (with the highest shipping cost) whereas all items travel at no additional shipping cost.
We have it programmed so that, when a buyer goes through checkout, the system adds everything up and only applies one shipping cost, based on the item with the highest of such.
Mind you, there has been a bug on eBay since last month which affects some transactions.
Our sales have always been about 50% to out of North America destinations. That's where the money lies, not in depressed USA.
You must have your ship-to settings as "worldwide" and preferably clearly state shipping costs, otherwise your listings will not be visible on other sites or, if visible, less sales as buyers are hesitant to buy if they don't know shipping costs up-front.
