At this point it is really nothing to get angry over, you didn't lose anything other than a few minutes of your time....
I also lost the money because I turned other people away because that loser told me that he was going to buy the figures then came up with excuses not to.
You hadn't even made a deal yet, you were in the process of doing so, he didn't like what he saw and backed out before he made a commitment. There is nothing unreasonable about that.
No, he did make a commitment to buy the figures.
