TOD: Just a couple of little things before this.
I gave a small amount to an acquaintance's Kickstarter campaign to get a CD funded. It wasn't even something I was interested in, but I wanted to help the person at the time. I gave the $20 or whatever it was, got the CD, and quietly passed it on to someone.
Another thing was $15 or $20, out of which I was supposed to get a book...and never did -- and I'm pretty sure a friend said the same thing happened to them. It's been a while, but in thinking about it now I'm just pissed enough to go back to them and ask WTF, just on principle.
