hi guys thread dig-up as i'm in japan and some insight into places mentioned previously!

Ikebukuro: 2 department stores had almost nothing, 2 items (demolisher and something else)
Kiddyland Harajuku: Decent stock of everything but way over-priced compared to what else I saw
Yobodashi-Aki (level 6): Overpriced
Random stores in akihabara: Well priced, will pickup buster prime for about 6200 YEN, MP Thundercracker for 6100 and some other bits and pieces in the coming week!
