So together with eBay’s 2005 gross merchandise sales of $44.3 billion minus eBay’s automobile sale of an estimated $thirteen billion, and assuming that two thirds of remaining eBay gross sales could equate to retail gross sales (versus individuals simply getting rid of stuff) complete on-line sales in 2005 shot as much as $107 billion. In 2005 gross merchandise sales rose 30% over 2004 to $44.Three billion.
