As a result, I did much research and compiled as comprehensive a list as I could, both national and international, and put them up at used-stamps.co.uk.
The site has had 30,950 hits and created many comments and enquiries to me. Many charities have received stamps to help them raise money and it's been great to be the source of such a resource.
However its success has also been, I'm afraid to say, its downfall. I get so many emails telling me about new charities which collect stamps, or charities listed which no longer collect stamps, or from charities wondering how to fundraise with used stamps, or from people wanting rare stamps, that I cannot keep on top of it.
The list needs constant attention, which I cannot give it.
I considered leaving the page up with a note at the top saying that it was out of date and that visitors couldn't rely on the information provided, but realising this would cause hassle to the listed charities who no longer fundraise with stamps has now led me to remove the information entirely.
I feel sad! But I have to be realistic. In case anyone, for some reason, really really wants to see the final list, you can do so here, but I cannot accept any responsibility at all for the information there. If in doubt, it is best to assume it is out of date and not reliable information any more. Despite the work put in to it, times change quickly.
Last December I posted this information about a way to help charities fundraise with used stamps. It is perhaps the most reliable information and you can find all the info you need there.
