Depending on how old your nephew/niece are, you can take them to do a cheap, but memorable holiday activity. For example, you can go to an ice rink and teach them how to ice skate for < $15. Or maybe have a mega ice cream day (with approval from their parents of course) where you go play in the park (make / fly a kite?) and then buy several pints of ice cream and share it. You can make up for other people's generosity with their $$$ by being generous with your time. In short: experiences > stuff.
