I want to use a different address, but just on this order. How do I do that?

If you don’t want to change your default address but want to use a different address for a specific order, you can select the address by clicking the "Check Out" button and following the change billing/shipping address links. Note that after changing addresses, you will be returned to the shopping cart for your order to be recalculated as prices may vary based on shipping or billing address.
