RE: help me deal with this guy!!!
EddieC hit it right on the head. Ebay has taken away the seller's ability to rate the buyer so ANY buyer can hammer a sale for any reason and ruin a perfectly good sellers record in no time.
The seller has no recourse. Ebay knows they have the market cornered on internet selling and you play it their way or no way. PLUS you cough up 10% of the sale, like it or not.
It's obvious this sale is going to a buyer that is missing a whole bunch of marbles and you're going to get a negative feedback.
Respond with just what you told us. You missed the next day shipping so you sent it expedited. There's not a lot of text you can put in the response so let your buyers know your intent was good, buyer as a soda jerk.
