I have never understood why anyone would throw useable items into a skip (ie, into landfill). As others have said, house clearance firms will be happy to take the lot, including the rubbish, if you don’t want the trouble of sorting it yourself.
We’ve just been doing a bit of thinking ahead and have taken a full carload of boxes of football programmes, sets of magazines, old children’s comics, annuals, etc, over to a specialist Oxfam book store. I did check first that they wanted them and that none of them were worth thousands - many would have sold for a few quid but I didn’t want the hassle. I’m sure the charity would have collected them if need be, and we’ve gift aided so will get to know what they’ve raised from our stuff. One person’s junk is someone else’s treasure.
