Some people occasionally do a "free stuff!" post, and their friends can offer to take said stuff off their hands. There's an implication that said friends are going to bump into said people, for example at a pub or convention or simply by being within easy visiting distance, within a reasonable timeframe.
Is it worth my while doing one of those "free stuff" posts with lists of books?
It's 1:10am. Can you tell I fail at sleep?
