I haven't dealt with Lightinthebox.com and Chinavasion.com myself but if you search throughout the forum, you'll learn to be very cautious when dealing with Chinese suppliers as most branded goods that come from China are either replicas or fakes. Their products may be cheap but you can't really be a hundred percent sure that these are authentic brands as advertised.
Generally, Chinese suppliers are best suited for cheap, generic goods. Because so much of the worldâ€™s goods are now manufactured in China, you won't find anything cheaper anywhere else. However, if you wish to purchase brand-name items, then we STRONGLY recommend buying it somewhere else.
