If you like bargain hunting, reusing materials, and supporting a great charity at the same time, you should check out the Habitat for Humanity ReStore.
I discovered the ReStore on Winchester Rd. when I lived in Memphis. Now in Austin, I frequent the store here, which happens to be the first location in the country. The store carries new and used building and household materials, which have been donated by businesses and individuals. The proceeds are used to fund the construction of Habitat houses within the community.
