Purchasable \Pur"chas*a*ble\, a.
   Capable of being bought, purchased, or obtained for a
   consideration; hence, venal; corrupt.

         Money being the counterbalance to all things
         purchasable by it, as much as you take off from the
         value of money, so much you add to the price of things
         exchanged.                               --Locke.
