Just because the 3rd film doesn't have "Dollars" in its name doesn't mean it wasn't part of the trilogy.

It was indeed part of the Leone/Eastood trilogy; it just wasn't one of the two "Dollars" movies.

The trilogy is what is unofficially referred to by fans as the "Dollars trilogy." All 3 movies are considered to be part of the same series of spaghetti westerns. If you don't believe me, Google search "dollars trilogy" and see how many hits you get.
(geez, why are we arguing about this? This is like Clinton trying to argue what the meaning of "is" is...)
