I found a big cardboard display of the mission series figures at the local Kohls. They are supposed to have a dedicated endcap for all the Rebels stuff, so worth a shot if you're looking for these. My store had the Sabine/Wookies wave. Only downside is that the figures are $15.
I am burning through some gas going back and forth between the 3 Kohl's in town trying to find that #$%^&* Sabine variant.
NONE of them are stocking any 4" SW figures, not even crappy old ones. All they have are those 12" ones.
I did see a huge standalone Avengers display though, with all the newest MU waves. So I guess they got all the love around here.
