Thanks to everyone for their input. Like Sea-to-Sky said, I usually TRY to take the high road when dealing with sellers OR buyers....but this guy just ticked me off, so I can see where my email probably had overtones.
Anyway, I sent him an email apology and paid for the auction today. Just to stir the pot, I was thinking about emailing HIM tomorrow and asking why the figures aren't here yet.
Hopefully he gets over it and gives you all the mini's and in good condition.
