Yes, i do and lots of people do where i live. However, it gets irritating that this seems to have led to a pervasive minority who are quite grabby and want everything for free.
Eg there's a lady where i live who will post constantly on local groups asking for things.
"Is anybody looking to get rid of an iphone"
"Looking for a kids bike, 14 or 16 inch good condition"
I messaged her about the second, saying i had an isla for sale. The reply was "i'm looking to get one free". Its take take take and a sense of entitlement.
Often these people will post with a very specific wish list "looking for the school uniform jumpers, age 9-10, must be the newer logo & in very good condition". I couldnt help it, i replied saying "they sell them in the uniform shop".
