Replying to [drdonmm]:
There many real suppliers on Alibaba but like anywhere you will get the odd ones that pop up and cause problems.
The main thing is for you to have more understanding about the products and the business in China as suppliers.
Do you own due diligence as its your business and money.
Tom Tom GPS in China, well i have never seen a real supplier to date, all i have seen are scams.
China GPS products will not be cheap on the market place, i can buy in UK for atop brand at £69 with maps, why i should pay £50 more without maps and no branded?
Check the prices before you send money, and if products are branded most common to be a non factory, so how are they getting the products, like Nokia phones we see suppliers selling copies, just like the real phone without the brand name.
Good luck
