I get the breaking his word part. But if you are good with scalping, then you should be ok with this guy reneging on the deal. Seems to me, at least in my experience with that lot, that that is par for the course. Particularly in instances when the price goes from double retail to triple retail in the course of mere days!!!!!
As the price kept climbing, your deal went further and further in jeopardy...and from your nervous post, you knew it was.
I feel for you bro and I hope the guy, whoever he is, renegotiates the deal...if its about money. If he just wants to keep it, then I hope your WL converts with the rest of ours.
