If you have seen Darth Revan figures on most shopping sites so its not that rare why is it 49.99?

The Darth Revan figure is somewhat of a limted edition figure that was only released with the Anniversary Collection. The Darth revan action figure is roughly $80 now while the Darth Malak figure is about $50. If you were to purchase one, I would suggest keeping it in its packaging, as it is rare and should be kept in mint condition.
