Bink, I think that the problem was around the word IF in the offer. It was not a firm offer unless the seller agreed to certain criteria. In my opinion, this needed additional confirmation and acknowledgement to complete. The 10 minute time limit is what is unacceptable. In a reasonable exchange, there would have been one email agreeing and one more from you acknowledging. Another point to consider is that there are a lot of flakes that make "offers" and never follow through, leaving sellers stuck. So this person may have had a bad experience and is still trying to figure out where common ground is.
Like Sean said, consider yourself lucky that this is all that happened. Best of luck in future ventures.
