I was charged $4.99 when I thought and saw advertised it was free.

Sorry to hear that. There might have been a couple hours when iTunes store gradually updated the price at midnight at each timezone, and the description still said it was free? Either way, if it wasn't free, the button you clicked to download should have showed you the price.
Anyway, if you purchased by mistake, you should be able to get a refund from Apple (in itunes -> account -> purchase history -> report a problem -> ...).
