I've told my kids that there is value in my stuff - IF they are willing to put some time and effort into selling it.
On the other hand, if they just want to get it gone - well, that's up to them when the time comes.
I have asked them, though, to please, please, please, not dump it in the trash.
A lot of people have 'scored' - did they pay a 'fair price'?
If the seller is happy with what he/she received, I guess that's good enough.
