TO SPECIFY YOUR SHIPPING ADDRESS:
WHEN USING YOUR PAYPAL ACCOUNT FOR PAYMENT:
Click the Edit link next to the default Shipping Address and you will see a popup window with your predetermined list of addresses from Paypal. Select one of these addresses if you'd like to change the default address.
WHEN USING YOUR CREDIT/DEBIT CARD (NON-PAYPAL MEMBERS):
Uncheck the box "Shipping Address is same as my Billing address" and enter the shipping destination of your choice.
