Checking the sales history for a particular type of item is an important step whether you’re buying or selling on eBay. If you know how much similar items have sold for, you can avoid overbidding on an item and instead wait for a new auction with less competition. If you’re selling, you can use the information to avoid underpricing or overpricing your own item. You can also view the sales history of your own items from the My eBay section of the website.
