Time passes, and I get a message from the seller saying they've run out of stock would I like another decal?
(No, thanks, just a refund, please (waiting on that but I don't suspect it will be a problem).)
This isn't the worst bad_service ever (obviously) but.. why sell something as "having 3 in stock" on ebay when you're not even going to make sure to reserve that stock? In fact your auction still says 1 sold (being me), 2 available.
(P.S. I understand when store website inventory is wonky/delayed but I don't think this is the same at all as someone had to physically list it without checking/reserving the inventory, and leave it listed after realizing they were out.)
