Reason: If you are looking for good quality product, you are at wrong place(site), they sell everything everything. Not even duplicate they sell some non-authenticated product.
Take Example of this Nokia BH503 Headphone, where other ecommerce website sells on very high rate shopclues selling in just 999, with the discount of 30%. When Amazon has very high rate. Amazon has record of selling original one, so I can bet Shopclues has duplicate/OEM one, where they have no where mentioned that. See below LINK.
