I just purchased it this afternoon. Costco has a very good refund policy, if not the best, so I'm not worry about any problem that I might have. Since I'm inexperience with bike mechanics, I'll probably have to pay $40 for my LBS to tune it up. This would be my second purchase of road bike after my first Giant OCR3, which I've lost a few months ago.
I'll write some reviews once I receive it, but then the sale would be end at that time. If there is a Costco close to your house go buy it because you can return it later. I've tried to return a software back to local Costco, they even refunded the shipping cost, Costco is the best, gotta love them.
