I sell a bunch of stuff on eBay, over 12K transactions to date. (Mostly non pin stuff) I see your issue. NO one in their right mind expects overnight shipping on a collectible item unless they pay 3X normal shipping cost. Plus no sellers offer it unless game tickets with an expiration date. I get the ship ASAP crap all the time, everything goes out the same day or next. I have a 100% ship rate as you probably do as a top rated seller. There is the 1% a-hole factor and you met yours.
