The receipt I got in my email shows the payment information, but doesn't have any link to directly print the materials — just links to Activate PayPal. I tried to print the email directly through Yahoo but the output was spread across three different pages that split up the order information.

I actually already have a PayPal account, but it wasn't convenient for me to use it at the time of ordering. Logging into PayPal through the email does nothing to show the transaction information or apply the order to my PayPal account.

Edit for clarity: This is a domestic order, not international. The Activate PayPal links both inexplicably redirect to a Forgot Password page with my email address in the given field. The email I used for the order is the same one that is tied to my PayPal.

It doesn't come with a shipping label, you need to send it out yourself.

If you can't print out a receipt, just write a note with your name / address / email.
(Or if the return address on the package matches the address on your order, that's good enough too. I just need SOME way to identify the 3DS)
