I only fill bags which benefit the local air ambulance service, as I know the bags picked up door to door are taken to their large shop/warehouse and decent things will be sold, rather than just sent for recycling. Smaller items I take into my preferred charity shop in town. Years ago, a friend alerted me to the scams, when a British Heart Foundation bag dropped through the letterbox, marked that it would be collected on a Saturday, which he knew the bona fide organisation never did. The British Heart Foundation do home collection Greenfinch, but don’t know if they are in your area. They also take electrical items and furniture.
