There are pros and cons to using this method of sale. The pros: you aren't going to have to worry that your shoes will slip away from you for less than market value. The cons: you might make less money than you would if you let people bid and two or more people really want your shoes. This method gives you a little more control on the final price and if you need instant cash, a fiend might even pay more than market to get them ASAP. But be careful and don't undersell.
