Which charity collects used postage stamps?

The Royal National Lifeboat Institution, The South Devon Players Theatre Company and the Children's Safety Education Foundation all collect used postage stamps for their charities. However, several more charities accept used stamps.

Typically, a charity accepts used postage stamp donations then finds buyers or collectors to sell them to. Once it sells the used postage stamps, it uses the money for the charity's needs. Some organizations collect used stamps and then divide them up among many of the charities that need them. The stamps are cleaned up in a way that the value is not destroyed, and then they are dispersed.
