WTB/ISO: Darkrai Organized Play Cap
I bought one of these and the seller lied about shipping it out and then ghosted me. Luckily I got my money back. You can find a couple sold in the past, so they’re not unfindable.
Right now what I can pay is $35 + shipping.
Hoping somebody can help me out after such a bad experience. 
I will be on the lookout! How did the organized play events work? I wonder if anyone may have participated back in the day and still have one.
These were usually given out as door prizes or entry “gifts” for participants at States/Regional+ level events.
Currently every player gets a playmat, but back in the day sometimes you could choose playmat or hat.
I would guess these specific Darkrai hats were given out around 2009-2010 (you could pin this down with the Pokemon Organized Play vs Play Pokemon distinction, probably on the back of the hat) (EDIT: says Pokemon Organized Play on the side so must be pre-2010), and there are probably a decent amount out there so I bet one will turn up eventually 
Thank you for the info! I hope I can find one soon.
