Update 9/14:
Ended up getting a few more boxes since the last post. Updated list is here: https://docs.google.com/spreadsheets/d/14mXfbRP7Fs2tX14PKM1p1kXTiR9gX02P5DARnry2rKI
I'm located in the US. Preference for trading, but willing to buy and/or sell depending. I have a few boxes of B22 preordered -- I'll likely update this list again when I get them.
