USA FLAGS
At USA Flags, they have an easy to use, online flag donation tool, pairing your flag up with someone in need, local schools or other organizations. Sign up is free and only requires a valid email address, just post your flag donation information on their site and then someone will contact you. USA Flags sells Endurance Flags, which is a small family-owned business, devoted solely to making American and POW flags.
