Welcome to SaleHoo, Hamza!
If you wish to purchase brand-name items, don't use Chinese suppliers as the vast majority of brand-name goods that come from China are either replicas or fakes. Assume that this is the case in the first instance. Generally, Chinese suppliers are best suited for cheap, generic goods. Because so much of the world’s goods are now manufactured in China, you won't find anything cheaper anywhere else.
DHgate is a directory of suppliers. Below are some posts about DHgate that you might be interested in reading.
