I use Freecycle/Freegle a lot for this sort of thing. Community projects are often looking out for items such as paint (even used paint, wood, odd rolls of wallpaper) and gardening items (tools, chicken wire, flowerpots, leaky hoses!). All 'doorstep collection' too.
We use Freecycle all the time. It’s amazing what people will take off your hands. We are tidying up the back garden and last week we disposed of several planters and nine paving slabs. Next is the shed - we have too many garden tools, I’m sure we will pass them on to somebody. Then we will tackle the garage, DH doesn’t take on so many DIY jobs as he used to so there are things in there he will never use, somebody will take them, including tins of paint, thanks for the link midgey
Sometimes we juts put things at the end of the drive and often it has been the couriers who take unwanted items for you. Other than that I just out everything on Marketplace some of it it sold and some FOC. All our unwanted clothes and household linens go in a bag and popped in the Salvation army containers which are prolific round here and as the charity shops have got very sniffy about what they will and will not take we find the SA takes everything.
