The local Target put out a case of these on Friday during the huge anticipatory TF movie toy reset, and both Chewies were, like Spuffy's experience, mysteriously missing from the case. Grabbed one of each of the rest along with an extra Stormtrooper. The Wal-Mart just down the street apparently got a case as well, as there was still a Stormtrooper and Vader hanging around on Saturday moring. As of this morning, all that either store has left from this wave is Vader (3 at Target, 1 at WM).
Just an FYI to those of you who haven't gotten the Vader (which, by the looks of things, is everyone but me): the figure is essentially identical to the ANH Commemorative Tin Vader, right down to the same Hayden scarred head, making Hasbro's argument that they wouldn't release an Evolutions ROTS Anakin on a card due to his inclusion in the ROTS tin null and void. If there are differences between the two (other than the Obi-Wan cloak), they're so miniscule to be unnoticeable.
My Biggs has the same foot problems as Spuffy, too. His feet look like the Wicked Witch's toes curling up after the house lands on her.
