Replying To [Shooshla]:
There are NO security measures in place, as alibaba do NOT get involved with any dealings between Buyers and Sellers.
Alibaba is purely a B2B website that puts Buyers in touch with Sellers.
Western Union?????
I would be concerned, as once the money has been sent there is no recourse.
I am making an educated guess here, that maybe you are planning on buying a Nokia Phone, PS3 or some other BRANDED electronic product.
If so, run for the hills, and keep your money, as it WILL be a scam.
You send the money and get NOTHING in return.
