Time travel is apparently real.
In my email and my eBay messages was my Dec 2006 Invoice notification.
I clicked the "see invoice" link in the ebay message, and it took me to the 2006 invoice!! The real one from 16+ years ago. When the eBay billing address was eBay Switzerland.
Is this why sales are slow? They think I owe $19 CAD from over 16 years ago???? I swear I paid it LOL!
