Most of Catherder's post applies to selling on eBay in general.
Currently, I have an interesting problem. The buyer says he see his correct confimed address in his Paypal profile, while I see a different confirmed address for him when I go to print the shipping label. In fact the shipping system errors on the address I see and says it is different from the U.S. Postal Service's recommended address. The recommened address is what he says he sees as his confirmed address on his account. If I ship to any other address that what comes up as the confirmed address, I am not covered by the protection policy. Doesn't matter anyway. If I change the address it will not let my purchase the shipping as it is not the confirmed address for the buyer.
