The folks here normally buy direct from trusted dealers in China via international courier service. If the piece is in stock, you're looking at 5 business days door to door. Airmail is a slower but cheaper option and takes two weeks.
Look at the top of this screen, and click the FORUMS button, then scroll way down to Watches, Clothing, and Accessories to find the listing of trusted dealers and their web sites.
If you really want to buy from within the USA, then look at WBK's sales area here. He ships from within the US but he only stocks "Canal Street ++" quality replicas .. nothing high end at all.
He does not carry junk but he does not carry the best stuff either.
