I JUST had an auction end and I sent the bidder an invoice. minutes later, I get this. WTF?! why does this always happen to me. I sent a second chance offer, but I'm sure the person won't take it. see, if it were me, I wouldn't risk a negative for $30. I'd just say oops and pay it. it's not like $600 vs. $900 or something. what are my options with this? mutually withdraw the transaction?
