i totally agree with Des and i do exactly the same.
any ‘good’ clothes we no longer use, i personallly deliver to a charity shop or give to the dochas orphanage collection.
if i know a collection is a scam, i leave out the blankets my dogs sleep on and any old rags i’d be ashamed to send to the charity shop.
it’s a way to teach the scammers a lesson and saves me paying the extra weight in my weekly refuse collection!
