I used to be a middle school teacher, and I was always searching for project supplies on the cheap.  I remember learning about the Creative Reuse Warehouse in Chicago and wishing we had something like this in my city.  Creative Reuse Warehouse collects business byproducts, overrunns, & rejected items and sells them to teachers, artists, & other local organizations. 

During my Google search to relocate Creative Reuse Warehouse, I ran across other businesses like this across the country!  Additionally some of these businesses have arts classes, galleries with art from reused items, open studio space (with free beverages & snacks), camps, and community programs.
