Yes sorry it was BIN, so long ago that I had forgotten. BIN means that the seller offered to sell it at that price so one would assume they were happy to accept that price. Does it matter whether it was BIN or not? It was a binding contract regardless.

Well if the seller can just cancel it and refuse to provide the item without having the courtesy to inform me, or offer any explanation as to why they cancelled it, then I guess the only option is to leave appropriate feedback.
