^ It's disgusting from seller's pov.
Pretty sure that only the SELLER can start the process, even when buyer is deadbeat - SELLER must send a request to cancel. Then buyer has 2 weeks (IIRC) to reply.
One deadbeat BUYER sent me note - "I don't want to buy, please cancel it for me." And then I had to initiate the cancel process. Twisted, counter-intuitive, illogical, whatever, it's the ebay experience.
But then you can't leave deadbeat note in the rep comment (still must be a pos, but you can describe that buyer is deadbeat).
Or I suppose SELLER can wait a few days then start a 'dispute' that BUYER did not pay. I forget the tortuous route that one takes, but I think it's the only way a BUYER can accumulate record of being a non-payer bidder.
[Anthony's art/comics sent me wrong ASM 10, then said he didn't have the right one to ship me, a disappointment to me, and I just went away (return/refund), stuff happens; sorry you got stuck with a dud, Dan.]
