I also like the idea of switching it to an info site on the subject. You can use the sites good rep with SEs. It could do well monetized with ads.
The other option is to contact a competitor and see if they want to continue to run the site and sell them all the IP.
Often times these big sites have smaller sites that send all orders to the "bigger brother" to fulfill. That way people who don't want to buy at "Big store dot com" will buy at "small store dot com" not even aware that they are one in the same.
