Hi as you know that now these days many shopping sites growup and sell their item and deliver at home. Top most sites like flipkart, amazon etc. But ebay also.a reliable site to buy. Ebay prices are much cheaper than other e commerce site so please compare from ebay. Ebay gives you few paypal points aslo that you can redeem on your next shopping. Ebay has also bidding market where you can buy through bid.
All in all you must try at least one time. From my side Ebay is a reliable e commerce web site. So go for it.
