The Costco where I work has a novel way to raise money for "The Childrens Miricle Network" (I'm sure you've been asked to donate at every store you shop at). We bring food from home and sell it in the employee break room with the money going to the charity.
Today I did 20 pizzas (the pizza oven there does not do a great job with the crust, but it was passable). I wish I had remembered a camera so I could post this on "My Pizza Monday" but I didn't. It was a big success though as everyone was taking 2-3 slices
