Are there online sites available to US buyers other than ebay?
With the help of Google translate I looked around the Polish site - http://www.allegro.pl/
I found some interesting watches that I haven't seen on ebay. Of course, bidding on a piece and paying for it would be more challenging than browsing - maybe impossible.
Are European sites an option for US buyers? That is, online auction sites located in Europe, primarily catering to the local market, but available to US buyers in some way - the seller will ship to the US, for example.
