I would have done $28 for Artoo and Threepio.
I can't justify that much for Dengar and IG-88. Maybe I would have if it was Bossk instead of Dengar, but he is the absolute worst figure choice for this format IMHO. I won't keep a big box or these carded at all, and I can find pretty minty originals for less than this.
Hasbro is still testing those boundaries.
