So if you don't have whatever it is, you don't need it, so therefore it has to be free to you, or it's worse than useless. Anyway, it's probably best to assume any unsolicited gift is free. If you're wrong, that's the last time you'll ever have to think about it.
Maybe keep a bunch of those little Chinese puzzles on hand for a handy little thoughtful payback
