I'd say you did just fine. The .44-40 at 15 cents per case is a bit under half of what new Starline brass is going for. And the bulk price on the .45Colt and .44Mag is certainly a "START THE CAR!" price if the brass hasn't been shot a whole lot of times to where the rims are flattening and mushrooming out.
Don't laugh you lot. I saw some .45Colt used for cowboy action loads where it was shot and reloaded so many times that the head stamp wasn't visible any longer and the rims had been beaten out so far by this flattening that they would not chamber properly any longer because the rims were touching each other on the back of a revolver cylinder so they would not lay fully into the chambers.
