I'm glad you explained it... it is very strange and unexpected to hear the details of this story. Luckily it was only 0.01 BTC and not much more.
I would give them another 6 months and then email them again BEFORE sending any BTC to see how they answer your possible question about Bitcoin with out using coinbase.
I'm happy overstock is trying to take Bitcoin and is constantly in the news about it. We need these big companies to keep trying to accept it.
