Sorry to hear that S5D.
Actually I tried to buy at mlbshop.com in the first place because I thought that it should be safe and the service should be oks.
A year ago I bought some jerseys at a web page which after a while I found out that was chinese as well —not sure if it is the same you are presenting, but the name sounds familiar. My order arrived but it took like 3 months. The reason? They send their stuff via the postal service and not a carrier like dhl, fedex, etc.
Said that, IMO you still have chances to recive your stuff S5D. Good luck my friend.
