Looks like pretty much everythig is showing up at Wal-Mart or Target.
Wal-mart has/had the Zutton and Eeth combo's along with the first two 25th aniversary 2 packs.
Target has had a small steady supply (Depending on teh day) of FX-7, Queen Decoy, Imperial Officer, and Rebel Trooper, along with the Wave 2 Deluxes and 25th 2 packs. Also some Targets have a few of the older waves on clearance for $4.50...not much left. You may also catch a 12" speeder bike in a box that has been beat to all living H@*& for $27.90.
TRU hasn't been good for much except if you catch a new deluxe for the cheaper $10.99 price (Vs. Target's $15.99).
K-Mart is still overstocked in old waves.
Good luck on the search!
