I've seen/read someone buying a PKMP when magic RSed them at 1.1m~ and the actual price was like 400k or less, made a board and his friends basically returned him his 1.1m~
From me, haven't lost that much.
I've also heard from a friend that used Joe's list included with SBP and got like 2 junk MPs (Ogrin ones, IIRC) LMAO
