I usually don't wade into these topics, however, I suppose I'm going to add my two cents...

From where I sit (unbiased and objective) in the nosebleed section, it is my humble opinion that BOTH the seller and buyer could have (and should have) handled this better. From the outside looking in, there's plenty of discrepancies and questions unanswered by both parties.

Mark, whether you believe yourself to be in the right or not, you certainly haven't done yourself any favors. I'm glad you've expressed your policy and attitude in regards to how you conduct business. Based on this, I definitely will NOT buy/sell/trade with you.
