They are available in various sizes and depending on your project or your needs you need to purchase the right size. It is amazing that something so useful is sold at inexpensive prices, so you should stock up on these if you are into woodworking. You can purchase these from tool auctions or you can visit your local store which sells woodworking tools and items.
