VMP customers can change the address for future shipments by accessing the "Profile Settings" tab of their Membership page. Keep in mind that this will not affect any outstanding orders (including pre-ordered titles). Send us an email at firstname.lastname@example.org if you need to modify the shipping address for any outstanding orders. Unfortunately, we're unable to modify the shipping address for packages once they have shipped.
For domestic customers, keep in mind that USPS mail forwarding will not work with VMP shipments, as they're classified as Media Mail.
