That's a punk ass bitch alright. I don't know the age, but sounds rather young...

When I was moving to another country and selling my things there was soo much of this kind of wishy-washy bargaining, people not showing up on time, disrespectful attitudes... And I'm pretty sure you can find similar stories circulating online about crazy experiences people have trying to sell things on FB Market Place, craigslist etc.

Similar mixture of this type of punk-bitchery was also happening when I was an Airbnb host. People would ask for deals, then not respect the clearly-stated rules, come up with dumb excuses. Luckily Airbnb disputes dept is very pro-host and I won every time.

I guess what I'm trying to say is that this happens more often than you think, and its not a reflection of something that you did wrong. But it is a good place to establish some boundaries as a seller. Maybe if you spot two signs of a bad buyer, just tell them you have other inquiries and let them marinate in their Fomo.

Anyway, I don't know anything about snowboarding, but these bindings look pretty dope, I wish you luck in selling them for what they worth, and to an informed buyer.
