If you need to get your hands on a a few pre-owned Skull Scorpio sets for some MOC building, this lot of four is one of the cheaper prices I could find available in the U.S. region. For $60.00, your paying about 17.05 each after you calculate the shipping, unless you happen to live close enough to Vineland New Jersey to do a free local pickup.

You might be able to snag them individually for a little cheaper if you only need one or two, although any more and the cost of shipping from multiple sellers could quickly add up to more than you would save. These also have the added benefit of including the original box and instructions, if you have some BIONICLE fans who don’t mind pre-owned to buy gifts for.
