I'm not rich, but I'm old enough not to have to worry about $25 here and there. For this project, I did give $250, which was the amount needed to get it across the line on the last day. Most projects are only $10-$50. Here's my list:

Personally, I find it very satisfying to give to a worthwhile project. I live near NYC where it costs $30-$40 for two people to go to a movie with refreshments. In many ways, Kickstarter is money better spent.
