Here's a list of charities to donate your good quality clutter to. If you have electrical items, plants, packing boxes or anything else you don't need cash for you could offer them to members of Freecycle.
I also wanted to say thank you so much again for your services on Saturday.... really – how great was that – I have now also started on sorting out the bags in my bedroom - so you definitely kick-started something there!!! Just hope I can finish it.
