K-Mart has had many Hasbro exclusives before (Transformers, BeyBlade, GI Joe), but this is the first Star WArs one to stick I think...
Back in the days of Episode 2, K-Mart was originally going to carry the Obi-Wan and Jedi Starfighter exclusive along with a Jango Pilot plus Slave 1 exclusive, but K-Mart dropped them thanks to the onset of bankruptcy hearings and Hasbro's unwillingness to extend K-Marts credit.
K-Mart couldn't pay for them, so Hasbro dropped them. The Obi-Wan set, having already made it to production was sold through KB Toys, but the Jango Pilot Slave 1 set was scrapped.
So, K-Mart has had exclusives before, but nothing this HOT before... these should sell very well for K-Mart.
