Fixed price is included but Buy It Now is not.
If you did a Fixed Price auction then it is set at only one price. You see one price, Say $9.99, and that is all you can get for it. There are no bids.
If you did an auction with Buy It Now you would see 2 prices. The starting price say .99 cents and a buy it now price say $99. They have 2 options. Buy it at $99 or start a bid at .99 which would effectively remove the buy it now. That is unless a reserve is placed on it.
