Their price tag is interesting. They initially display $250 to get you start thinking about its value, then about a second later animate its drop to $199.

When I first saw it, within a split second I judged it was probably worth $250. The drop to $199 left me feeling like I just saved $50. Somehow it was more effective than the "but wait, there's more" bit you always see in infomercials, perhaps because it was unexpected.
