The best deals you will find at Costco is on Hard Cover Books. Typically I can find all major new releases there for between 12-15 bucks, compared to paying 25-30 at Borders of Barnes and Noble. Their video game selection is pretty paltry, sometimes they have new titles on the day of their release, but this mostly only applies to major releases ie: Madden, Halo, GTA, Mario, etc. They are generally abotu 5 bucks cheaper then the electronics retailers. The only place where Costco falters is their DVDs. They generally have a much smaller selection and higher prices then Wal-Mart, Best Buy, or Target, so I would avoid shooping for movies there. I've also heard that Costco has the easiest return policy of any retailer, and will give you cash or at least credit for seemingly anything and everything, open, sealed, used, or new. Not sure if this is still the case though.
