Sony Corp. issued a warning Tuesday against false promotional offers for its upcoming PlayStation 3 video game console.

A number of Web sites have been promoting pre-orders on discounted or bulk shipments of the game system - without the cooperation of Sony, the company stated.

Company representatives did not name the sites but suggested consumers can avoid potential scams by purchasing PlayStation products only from authorized retailers and resellers, which includes well-known stores such as GameStop, EB Games, Best Buy and Wal-Mart.

The PlayStation 3 system, with models priced between $500 and $600, is set to go on sale in the U.S. on Nov. 17, though only in limited quantities.
