Let me tell you my own experience. I am not the type of customer who do online shopping regularly but I am in a need of a pen drive and memory card from some time. Initially I thought to purchase from the market personally because of a reason that I can practically select and buy these products after checking and bargaining both.
But, after analyzing that these product prices are not much comparable as that of online content available in many websites, I tried to search deeply in internet and found both these products as combo in ebay website. This combo product is very economic as compare to the market price and I also used the discount offer via discount coupon and get the product at less price. I received the product from ebay via courier service today. So, Timely and satisfactory deliver of the products makes the ebay website reliable and customer friendly. Such qualities are the need or demand of the market and society. Over all, to purchase any online products, ebay is very much reliable approach for purchase.
