I'm getting through "The World is Flat". It's a great book, if several hundred words too long (get an editor Thomas). It's opened my eyes to what can be achieved when you look a little further afield than you would normally. Already I gained a small buying advantage buy going directly to China and bypassing the usual middle men involved.
The main issue in all this is trust. Yes it's great to be able to source from China and make a saving on budget. But how do you really know what you'll get when the world is only email flat? My point is that I'm only making a small order, I can't afford to visit the factory, it would wipe out my saving. So I have to trust the supplier. I hope I can.
