All items were donated by homeowners who were remodeling and no longer needed them. They are usually very high-quality materials, although obviously used.
We always have lots of windows and interior doors. Windows usually sell for $4 each for single pane, $10 each for wavy-glass panes (of which we have very few), and $15 for multi-pane sashes. Doors sell for $25-90 each, depending on condition. Storm doors are available, too.
We also have lots of sinks, including rare cast iron utility sinks selling for $40 and up. And we have several hot water heat radiators, selling for $100 or $150, depending on size (bring a strong back!).
Remember to bring your tape measure!
