Alright, I've got a legitimate OMG hat that I'm willing to sell for $40.
Usually gold goes for $2/mil, which would mean $2 * 24 (24mil is the LMP for OMG right now). That's equivalent to $48, which is almost a $10 dollar discount. You typically won't find an OMG this cheap, so the deal is in the purchaser's favor.
