"Costco's new policy is to allow customers only 90 days to return electronics--although they will extend the manufacturer's warranty to two years and set up a tech support hotline to help people with basic support issues.
The
new Costco return policy states: "We guarantee your satisfaction on every product we sell, with a full refund. Exceptions: Televisions, computers, cameras, camcorders, iPod/MP3 players and cellular phones must be returned within 90 days of purchase for a refund."
I posted this after finding it on CNET awhile back. While we get screwed with the big items it sounds like with a console you'll be safe. My cousin is a manager at a Toronto Costco and they haven't been told anything regarding the new policy but she says that they're told if a customer squawks enough just give them what they want because with the amount of bulk items they move it's a minor annoyance to issue refunds for reasonably priced items.
