There's better reasons to get a Jumbo Vader Chubby than to put your smaller ones in him. He's one of the pieces that kids go crazy for when they visit my collection, but to be honest, the $59.95 price was a bit steep.
Say no more... Gentle Giant has lowered the price for Rebelscum readers. Just use this special Rebelscum Jumbo Chubby link and he'll be just $39.95 for you. Though frankly, tell all your friends as well because this is the right price for him.
