To sell a card

Good news: Found a store that buys individual Pokémon cards! The clerk was absolutely amazed to see some of the cards I had.

Bad news: They didn't offer near as much as I wanted. Understandable, they've gotta make money as well, but I want my basement to stop flooding, darn it!

Good news: The website that the store uses to do price checking has a section where people can set up to sell through them, potentially meaning me.

Bad news: Ack, how do I do the thing!

Good news: A friend has helped me figure out much of how to do the thing, yay!

Neutral news: Next what I want to do is make an appointment with the tax person my parents and I go to every year to find out what sort of things I need to know going forward with this. I think this is a phone call I will be able to make without screaming. (The total I'd potentially make from these cards is enough that I'll almost certainly need to report it as income next year.)

Okay. Deep breath. I can do this.
