Interesting, because I received an email from Audioholics telling me I won.
In my case, I contacted AH after I saw that I had won and asked what I was supposed to do. IIRC, Tom replied that I should have gotten an e-mail from the company providing the prize (but I hadn't), and he contacted the company that then very prompty e-mailed me.
So, something might have gotten lost along the way.
EDIT: I just checked, and my prize was from Impact Acoustics just like the g-man's, and was one month earlier.
