Just for today and yesterday guy sold 14th Mega packs.
How can you trace that??
Stock levels from 2014-11-21 23:37:47 UTC to 2014-11-22 18:25:31 UTC went roughly like this:
3,2,3,2,3,2,1,4,5,0,2,1,-1,2,0,2,0,-1,2,1,0,-1,1,0,2,1,0,4,3,2,1,-2,-3,3,1,0,-1,1,0,1,0,5,4,3,2,1
No idea how you are supposed to tell how many actually sold though...
