>>12275612BW had wall clings and styluses, but only at TRU. Target had a BW "Art Book", which was a little case with postcard sized glossy images of various BW stuff (starters, trainers, etc)
BW2 had the coins in OP, also at TRU. I don't think any other stores had anything, but GAME in the UK had DS cases with B/W Kyurem on them.
TRU is always the best place to preorder the Pokemon games at because they always have something.
The coins are pretty sweet, and heavier than I though. I'd personally like them to bring the figures back but because it was so easy to abuse the system they probably won't do that. Hopefully they'll announce something though. It's bullshit they don't tell anyone until like right before the game comes out.
