No, I will not sell the item

I recently listed an obsolete piece of software. It had been (probably) been previously used, and I was not sure if it was something anyone else would find useful, but, it could go for a decent amount.

I got a message, "if the item has been used, it's basically worthless." Which, given the item, would not surprise me, at all. So, I pulled it and thanked them for their time.

They send back, "hey, I collect this stuff, I'll take it for $$".

Umm... how about "no".

(Note: it was a fairly niche bit of software. also very, *very* obsolete. Having worked for a software company that sold very, *very* obsolete software, it wouldn't surprise me, at all, if the software was useless once used.)
