My favorite materials shop is the saw shop where I earn my paycheck. We're lucky the company allows us to buy stock by the inch at their cost. They don't always have the particular material I need for any given project so these two online stores are my 2ed and 3ed favorites. Both will sell small quantities at reasonable prices.
