Why the prices of many items (i cheked 20 items) are higher than that on amazon,flipcart etc

I cheked many item like Philips induction,mixer,Mobiles-lumia and canvas series etc.I found all these costlier on ebay and much cheaper on other sites like amazon,flipcart,snapdeal.These sites are also trusted ones.So why ebay is charging high?
