I've opened enough Brand Buster boxes to complete extra sets. This isn't easy, since some boxes don't contain a full 30 sticker set, and some don't contain even one complete 9 piece puzzle checklist set out of the three possible (Bang, Big Squeal and Gamblin'). There seem to be 4 or 5 stickers that are short printed. There's no way a single box can contain all three complete puzzles since there are 27 pieces, and only 24 packs in a box.
I have a base sticker set with a complete Gamblin' 9 piece puzzle checklist set, plus an empty box, empty wrappers, an example of the glitter box toppers (Gamblin'), and some extra stickers for peeling and sticking fun for $90, shipped, or $85 without the empty box and extra wrappers.
I will consider trades!
