Well, I guess some of these won’t be too hard to find.
Hasbro and Walmart are helping celebrate the 35th anniversary of Transformers this year. Be on the look out at your nearest store for this cubicle display which features four exclusive Transformers War for Cybertron Siege toys in packaging branded with the annual achievement. Also in the cubicle is a mish-mash of Siege Deluxe and Voyager class figures from the last couple waves.
Looks like this cube has the four 35th anniversary offerings (Cel shaded Prime and Megs, Bluestreak, and Soundblaster) as well as a mix of deluxe and voyagers that may vary depending on your store.
