how to shop online??

You can shop online in many different ways, including eBay as you mentioned. I suggest that if you are going to shop online that before buying or bidding on anything, it is better to know the reputation of the seller, the product you are looking to buy and also the price (new and used) for the product you are considering purchasing. Also remember to take into account the cost of postage as there is no point in getting a 'bargain' if it costs you a fortune in postage costs. :)

The best way to find out that you may take sometime to do so but you need to have credit card or account like paypal in order for you to make any purchase.
