I was just at Costco and decided to get the scoop on their return policy. I spoke with a gentleman who informed me that, very soon, they will be changing their return policy to something similiar to what is offered currently for computer sales. That is to say, a six month limit. That is itself excellent, but not able to live up to their legendary unlimited open policy. He did inform me that if you bought your set in the last year or so then you would not be subject to the new limitation.
