Yesterday, I found Cloud Car Pilot, Cloud City Leia, and Lobot at Craig/Las Vegas Blvd. Wal-Mart (near Nellis AFB). They had 2 or 3 of each. I only picked up the Cloud Car Pilot - the others don't appeal to me, and Leia is so tiny...
Also, Centennial Wal-Mart had several of the following:
Dagobah Luke, Yoda, Spirit Obi-Wan, R2-D2 (I picked up 1 of each).
Also X-Wing Luke (only saw a couple), Han Solo (the same Saga version), Cloud City Leia, Lobot, and Chewbacca.
