No, I haven’t done any on-line shopping. But I know something about it. Just like if you want to buy something from a certain supermarket or department store, you will visit the store and have a close look at the item, you just visit the famous selling and buying websites. The famous ones are E-bay, Taobao and etc. You input the name and related information of the item you want Items which conform to your requirements will appear on the screen. You click the item one by one, have a careful look, compare these items, bargain with the seller, and finally order the one catering to your taste. You can tell the seller when you want it to be delivered and where. As to the payment, you can either pay it in advance or after you get the item.
