Table at xmas fair

They're having a fair at one of the local elementary schools and we've been
invited to setup a booth. There is a split on gross revenues with the
school. The fair is in a couple weeks so I don't have much time to get
ready. The school is in a  fairly wealthy community. I have zero experience
in this kind of thing.

I have a board game that I developed and I'll be selling it there. Since I'm
going to be there anyway, I'd like to sell some other things too. Puzzles,
craft supplies, games, etc. My thought is that there should be two price
points -- under two bucks for the kids, and under ten bucks for the moms.
(That's just off the top of my head.)

Its not a big school and I can't imagine more than a couple hundred people
showing up. If I have to overstock a little bit that's no big deal because I
can probably come up with another way to sell what's left. (Like having a
garage sale.)

I'm not looking for a major windfall here. This sounds like fun, and I hope
that my kids will want to help run the booth and so forth. At the same time,
I'm not looking to give things away nor do I want the kids to have a lesson
on how to loose money :)

The fair is right around the corner. I'm looking for items to sell and
suppliers. I'm open to suggestions.
