E-commerce is exhausting

I don't have a funny clip for this, because it's not funny. I've been trying to sell some old things on the internet and I've never met so many idiots in such a short span of time. No one seems to know how anything works, or how much it would cost to ship something. I thought I might make some money, but the amount of time I'm having to spend isn't worth it. Leading out from my Nerd hoard, There are some valuable comics in that load that are objectively shit. I've resolved to set apart the money earned from selling those and buying trade paperbacks. But the horror of what that might entail. What if they want me to ship something to the U.S.? Ugh...
