eBay-owned Shopping.com announced holiday pricing changes for its merchants that will be in effect November 15 - December 31, 2008. Shopping.com said the change was an effort to maintain its performance-based pricing model, "ensuring merchant selection while remaining competitive within the industry" at a time it anticipates an increase in traffic and sales.

Shopping.com will apply a 15% decrease to the standard CPCs in over 25 categories including GPS devices, MP3 players, video games, flat panel televisions and musical instruments. Shopping.com said it was not raising the standard CPCs for over 160 categories including all other electronics, computers and video game categories.

An increase of 20% will be applied to other categories like Clothing, Home and Garden, Kids and Family, Jewelry and Watches.
