Ebay.in is the indian online marketplace where different sellers can put their items. From my experience, what I recommend is that I you need to buy an item that not available online then only buy from ebay . Although ebay has many policies that are trying to take care of the customers still many of them are getting duped, low quality accessories are available on this which may look very much same to the original products .
You have to pay each seller differently for delivery, this is not always the case with other ecommerce .Cash on delivery option is not available from every seller:(
Go to it as the last option
