Ventured out to my local Texas Target store today and found about 30 40th Anniversary The Black Series 6-Inch Wave 2 figures. Some were on the 40th The Empire Strikes Back End Cap, and some were down the action figure aisle in the Star Wars Section. These have been consistently available at my local stores for about a month now.
Find it kind of odd that Target.com has a release date of 8/1 on this wave, while local stores have been selling them or over a month now.
In my area Wave 2 is pretty plentiful, but Wave 1 is still a bit hard to find. I think I only seen it once on pegs.
