I have never seen #5 at retail here either. Not even in Marshalls or TJ Maxx.
I had to get a whole case from BBTS just to get it.
Your best bet is just to try TJ Maxx, AJ Wright, or Marshalls. Or if you have a Tuesday Morning store I heard they had some too. These are all closeout stores so none of the regular stores will have any left.
Build a piece items only work well when every piece is available.
Then again all I want from the B-A-D Star Wars figures is the HK-47 droid!
