Thanks for the heads-up. Do you have some coordinates so we can call in an A-10 for a little BRRRRRT! action? Seriously, though, these scammers make me furious.
My first rule is to never buy anything off of a Facebook site other than Marketplace, which is always in-person. Most of the Facebook taco sites are just poor quality. While there are plenty of folks who are well-meaning, some questions are just, well, dumb and show you're just lazy. The answers are just as bad.
