Replying to [blackmarket]:
We are based in China and do check some companies for buyers, but we visit the suppliers and get information from them face to face, i know Ranger has many means of getting information about people and companies, but he as done this for many years, so you do need the background and the know how to investigate.
From the start when we first wanted to export from china we came here and met the factories direct, and i feel that the best way to start any trade business, we are dealing with large amounts of money i think a few days of your time and some money is a very good investment for your business.
Of cource you can use many people to go to the factory and check the samples take pics and send you the report, this again is better peace of mind.
Your choice, and please read many posts in the forums you will learn lots,
