T.K.
I'd rather swap for free. But yes, I would buy one to save money on a costume and help the school. It's much better than many fundraisers I've suffered through. I bet you could sell a lot of other things to the pareents when they show up for the swap too. You could buy colored hairspray or other dress up stuff in bulk and then sell individually. You could sell dollar store flashlights for $2. Glow Sticks, etc. If you have crafty moms, they could make up a whole bunch of capes to sell.
