Four major Web retailers today are jointly launching a shopping network featuring all the firms' products.
Financial terms of the deal were not disclosed.
The firms are banding together in hopes the added convenience of having all their products in one place will add to their holiday sales numbers.
With e-commerce booming, all the sites face stiff competition--along with having to attract customers from offline stores.
"This alliance of established e-commerce sites will make it easy for consumers to make informed buying decisions," Darryl Peck, Cyberian Outpost's founder, president, and chief executive, said in a statement.
The network will act as a giant referral service, with the participants sending customers to a hub page that will feature special promotions.
