I purchased off of cheapair.com using bitcoin yesterday and they use CoinBase as well for the merchant account. Extremely beautiful and seamless way to purchase, although I was a bit worried that it was actually just 1 button click to pay. I wasn't aware it was coinbase at first (I didn't read anything so partially my fault), but clicking the button made the payment and there was no verification. I would expect this to be a 2 step process. (I may have remembered this wrong, but I thought it was only 1 click to purchase)
