I guess you really have me confused now. If you shipped the strike that you put up for a "Buy It Now" option (item #6245766336) on 1/16/06, why would Kirk complain. He got a $600 strike for $100. You must have shipped a different strike than what was pictured in your auction, whether it was intentional or not. If you had shipped the item pictured, why would Kirk try to "switch" strikes. That just makes no sense.
