In the third quarter Overstock launched Eziba.com, a private-sale site that offers limited quantities of home goods that are available for a set time period, typically between 48 and 72 hours. Eziba is Overstock’s first private-sale site. But based on its success, the retailer says it may branch out into other product categories that take advantage of Overstock’s existing buyer relationships.
