Posted by llamatron in the Movie toy sightings topic, two more of the multi-packs have been found:
-Deluxe 08 Bumblebee with Voyager Optimus.
-Voyager Starscream Vs Battle Damaged Deluxe Arcee and Battle Damaged Voyager Optimus.

The 3-pack is definitely a store exclusive, and the 2-pack probably is as well.
Kmart have their big toy sale soon, so these could have been brought in for that.
