From their return policy page:
Some manufacturers have implemented returns restrictions that prevent CircuitCity.com from being able to accept returns or offer exchanges, replacements or credits on their products for any reason. Please check the item listing on our website to determine if special return policies are applicable to your products. Support as well as exchanges or replacements for products with manufacturer or supplier restrictions, including within the first 30 days of ownership, must be handled directly with the product manufacturer or supplier. You can find the manufacturer or suppliers contact information in your product manual, in the item listing, on the manufacturer's website or at our help center .
Apparently, select products from major manufacturers like Compaq, IBM, Hewlett Packard, Toshiba, Epson, Nintendo, Kodak and others fall into this list—but, as they noted, Circuit City does lay out the return policy for each item on its respective product page. I don't think it's something that should drive you away from CircuitCity.com altogether—but it is something that you should pay attention to should you ever make a purchase there. [Crunchgear]
