You can offer to sell it to them?

Back in the day, there was a big store 'Wiz' - "nobody beats the wiz!" was their logo. If you went to www.wiz.com (doesn't seem to work now), you got a private page - here's the way back machine: http://web.archive.org/web/20110512192129/http://wiz.com/

So if "the wiz" didn't take over that website when it was a big chain, I don't think you will have much issues.

I'm not a lawyer, and maybe this is an odd case - I don't know maybe the owner of wiz.com was a powerful wizard and that's why no one could steal their website.
