I have just listed my treadmill on Ebay, as my arthritis has put a stop to my 10,000 steps a day. I put a low starting price, to be sure that it sells. Within 5 minutes of it going online someone messaged me, offering £5 less than the basic price. Cheeky begger! I will let it run for a week, and see what the price goes up to.
I use Freegle occasionally, both giving and receiving. It can be a pain or a delight. In spite of putting 'no time-wasters' I had two 'no-shows' before a lady finally, and gratefully, picked up my old dining table. When I decided to pebble my front garden, to cut down on work, I Freegled a lot of the plants and met many nice people in the process.
I was about to bin a 1ft x 6ft strip of left-over vinyl flooring when I decided, just for a laugh, to Freegle it. To my surprise someone pounced on it. They were renovating a narrow-boat and "It will be perfect for lining the galley shelves!"
I also give things to charity shops. There are four a short distance from my house, but I usually donate to a lady I know. Her young grandchild died of meningitis, and she raises money for Meningitis Now.
I rarely bin anything, apart from the usual household things. If it's not good enough to give away I recycle it, or take it to the local tip, where it will be put to good use in some way or other.
