Just putting this out there: I gave him my shipping address, escrow has held my btc for a few days already, and OP still has not confirmed shipment or even responded back to me. You might want to hold off on new orders until he responds. At the very least, don't send him half the payment yet if that's what OP wants.
my escrow is couple of days old as well. I will pass with OP and this gopro. Thanks for option to forwarding this to me haploid.
