How can I find locally sourced goods and materials - both new and re-used?

Answer: 

Local newspapers often list a variety of used building materials for free or affordable prices! This applies also to community advertising websites such as Craigslist and www.gumtree.co.uk. The online auction site Ebay can also be a valuable tool. For earthship builders, visit your local tire store to pick up free tires! Finally, many cities are now starting to re-use materials from demolished buildings. Search around for your local re-use store. Talk to a local farmer to obtain straw. Good materials are everywhere, be creative and resourceful.
