Completed Listings eBay In this video I am going to show you how to find completed listings on eBay both on the mobile app and on your desktop. This information is really helpful when determining how much to list an item for as well as whether or not you should buy an item to resell on eBay. If items on eBay are not selling than you might not want to buy it. If an item is selling for less than it looks like than that of course is another indicator that you should probably not buy an item.
