That guy had noise coming from the seatpost - This is not the seatpost

I plan to take it for a longer ride tomorrow and try to get a better sense of what it is and what makes it tick. If I can't solve it I'll take it back to where I got it. The problem is the place is more of a general sporting goods store with a bike section, rather than a dedicated LBS so I'm not sure how knowledgeable their staff is on BB issues.
