mojolo: I purchased it around midnight at Walmart (only place open within 100 miles, LOL). They didn't give me any trouble returning it.
Norman Hunter: The Zune 80's sound has been "tweaked" by Microsoft. This is one of the reasons they give when asked about the lack of EQ. I haven't personally listened to the Zune 30, so I can't give a direct comparison, but judging from things I've read it is a little bit different. (Also, for those who don't know, the Zune 30 DOES have EQ strangely enough.)
