Do you have a PayPal account?
Have you added your shipping address to either your My eBay or your PayPal account.
this problem should not be a problem
Apparently it is, since you came here and asked about it.

You should enter your shipping address in http://paypal.com and mark it as your shipping address. Assuming you pay through paypal of course.

Your shipping and billing address do not have to be the same.
You can add multiple shipping addresses to your eBay account but make sure you choose the right one when you pay.
