I had an experience in buying physical goods with Bitcoin though a group buying site. I was able to buy a laptop and a smart phone. There is no physical contact from the seller that happened. But you still cannot remain anonymous, since buying online requires you post your shipping address and name.

Buying a physical item overseas is not a good idea if you ask me because of the time frame given from originating point to terminating point. Sometimes 1 month of waiting for an item is not worth it.
