You could swap your unwanted items or give someone else the opportunity to use them by donating them through one of the following online reuse networks:
Freegle website. For your items that are too good to throw away, but you just don't want them anymore. Why not take a look at the website and see if someone locally is offering something you might like?
Freecycle website. A non-profit group of people reusing items in their own towns. Each local group is moderated by local volunteers and membership is free.
