Second, in the search option -under Show only-, Tick at box in front of Buy It Now Items, then  find item condition and Tick Used items only. Then click Show items. Now you are watching items that will end in next 3,5,7,or 9 day. Most people only take care at items that ends soon. Uh-Oh, not smart enough,mate. Some people dont have any idea about their item's actual price, they will list their item with low price. And if you fast enough, you'll get it! Fast and cheap.
