The worst thing about Ebay which I have noticed is that its prices are higher compared to other online shopping sites and the quality may be duplicate which you might order from Ebay so think twice before ordering from Ebay because I think it is used by thug sellers and you will simply loose your money while shopping with Ebay.
There is also problem in delivery process you may or may not get your product which you have ordered on ebay. And product are 80% different from the product you might order from Ebay.So think befor you order on Ebay.
