... I just got an email from the play store... and it had nothing to do with this order. Good one, Google. You're funny.
BTW, on a serious note, I realized just after placing my order that the billing address for the order was old and not the same as the credit card I used for the order.
Surely that's fine, right? And if it wasn't, I would think that it would have already cancelled itself. The transaction is still in pending on my credit card. I thought about calling google about it, but am worried they might cancel the order trying to fix it.
Also, I've ordered an N7 through the play store before and I would think that the same billing address discrepancy would have occurred then, too. I should be fine... yep... definitely.
