Cost Plus World Market Treks off to the Kalahari With Six Flags Discovery Kingdom

National Retailer to Sponsor Giraffe Exhibit at Northern California’s Best Theme Park

Oakland, CA — March 22, 2007 — Cost Plus World Market (NASDAQ: CPWM), a leading retailer of casual home living and entertaining products, announced today that the company is sponsoring Nairobi’s Giraffe Encounter exhibit at Six Flags Discovery Kingdom in Vallejo, California. Cost Plus World Market will become an integral part of the guest’s experience, allowing them to get up close and personal with spectacular and exotic animals.

“Our stores are very family-oriented, much like the patrons of Six Flags Discovery Kingdom,” said Barry Feld, CEO of Cost Plus World Market. “These individuals enjoy travel and entertainment, which are exactly the product themes we carry within our stores. We are excited to be the exclusive sponsor of Six Flags Discovery Kingdom’s giraffe exhibit.”

Cost Plus World Market will begin sponsorship of Nairobi’s Giraffe Encounter beginning on the park’s opening day, March 24. Later in 2007 as part of the promotion, Cost Plus World Market will run an in-store contest open to Bay Area customers and named “Official Passport to Six Flags Discovery Kingdom”. In this contest, six lucky VIP customers and three of their guests will get to experience a behind-the-scenes tour at Six Flags Discovery Kingdom where they will be able to feed Shouka, the park’s orca, hang out in the dolphin pool, help give an elephant a bath and many more exciting, exclusive activities.

“We look forward to working with Cost Plus World Market on this exciting new opportunity,” said Martin Lathrop, Six Flags Discovery Kingdom’s Park President. “Because guests are able to interact with some of our spectacular animals, this is one of our most popular areas; it also helps people learn about animals and their habitats and encourages learning about conservation and the environment.”
