It's a wonderful idea - I was introduced to it by my brother, who had a number of items left over when he moved; not new enough to sell at a boot sale or with a small ad, but perfectly servicable. On our local group I have seen offered & taken recently - part bags of cement, rolls of wallpaper, sand, crockery, beds, chairs, fridges, cookers, bedding, fancy dress, bags of childrens clothes, bags of adults clothes, plants, egg boxes, bubble wrap, sewing machine, office files, etc etc! Thanks OP for spreading the word.
