I used to order batteries from Hong Kong off Ebay regularly. They showed up really quick.
All ebay auctions have a notation of where the item is. That is one of the things of Ebay, if it says Taiwan, Hong Kong, Japan, or who knows where else, it may well take forever to get. And the chances of it being a scam are far greater. Not to mention, what if it arrives damaged or incorrect? It isn't a matter of calling someone up and saying "Hey this isn't right". That is the risk anyone takes buying stuff from overseas on Ebay.
