Query: Why does Amazon have two seperate prices for this?

Okay, wonderful band. Saw them in concert. The Doc who plays banjo is...a little eccentric, probably on purpose. But once they started playing, it was delicious.With that said, WHY DOES AMAZON HAVE IT LISTED FOR BOTH $6.99 *AND* $9.99?? Who would seriously buy the 9.99 version simply because it's from a later edition CD? They are the exact same thing!WHY AMAZON WHY??Anyway, buy it--but get the 6.99 version.
