I had never seen Transformers Animated until very recently, I just hadn't been interested and I never bought a single figurine. I was doing a little browsing and there doesn't seem to be a very big market for second hand figures around.
Are the figures extremely popular and therefore not for sale so much? Or were they not produced as much as other lines?
Having almost no knowledge of TF Animated I'm curious.
