Ebay is one of the biggest shoping platform in the world , I love ebay but it has lots of hindrance to overcome like its not good to but expensive products from ebay.
If you are buying a expensive phone even above than 3-4000 you must buy it from amazon or flipkart as they provide good return process and policies with less process time , ebay is good for memory cards , powerbanks.
Etc as its give amazing discounts and offers to new as well as old users , it also hai refund policy but it takes lot of time to refund your money and another biggest drawback many a time you did not received your product after wating a lot of time
