I was able to track down Target's Exclusive Black Series 6-Inch Princess Leia (Bespin Escape) at my local South Texas Target stores this morning. Out of the 12 stores within 50 miles, 10 of them had 1 case (8 figures) in stock. But my local stores are not putting these out on the floor yet because of a new planogram and the mentioned Set date of 9/30, so I had to ask a employee to grab them from the stock room. I ended up buying 2 and asking for the empty case.
If you would like to try and track them down here is the DPCI: 087-16-0133.
