I have received quite a few of these so-called charity leaflets asking for clothes, furniture, even jewellery. Checked out 2 and found they are fakes. Second-life is one, the other one came up as an electrical firm in Hong Kong! Take your things to a charity shop in your area.
I am surprised though at the HQ’s of many charities. They have enormous quality buildings in quite expensive areas??? What percentage actually goes to help people? How can they afford to run these premises?
