@super11. That's true however some companies like dealextreme now have distribution centres in the US, Uk and Australia.
If you go to their website, there is a section for US distribution/warehouse products. They also have a dropshipping program that you can use. The only issue is that they have limited products. The only product that I think that would be of good potential would be the RC helicopters.
You can also sell some repair kits such as tiny screws and such from a North American dropshipping distributer such as Fastenal.
