None of that matters, they know who you are by your order number and then through corresponding e-mails after your order is placed. I.E: They e-mail you with your order #, you reply with your PayPal E-mail address, and tell them the payment is sent. You'll get an e-mail confirmation with shipping info and when to look for tracking etc. As long as you used the correct order # in your e-mail, the payment received from your PayPal will automatically be applied to THAT order #. This is the ONLY e-mail I sent them after placing my order and my e-mails aren't the same either.
I received my card in exactly 9 days from order.
