Man, I wonder how many facebook marketplace sales will be something like "In order to make sure you're a real person, before we can meet up so I can hand over this brand new macbook for $500 I need you to send me $10 electronically. It's really just to verify your commitment". With the right prompting, I'd be entirely unsurprised if Muse will just send over the $10, and of course the seller ghosts the buyer -_-
