The cost of the experience varies depending on the method used, start and end point.
Usually is 2.5-3m/h in afk method and 5-7m/h in intensive clicks method.
._Smithing= 40gp/exp (if gold ore @blastfurnace with gold gauntlets).
._Rcing is a special price because I can get 170k exp/h-230k exp/h, it's pretty expensive tho
