This is absolutely no help for you this year, but maybe for next year you can do things like Bing Rewards to earn gift cards. I've been doing that for a while. I'm sure there are other things like that. I know that in the U.S., there a places that give away gift cards if you show up. They aren't much, but every little bit helps. Maybe you could put an online ad asking for donations of what people have left on gift cards.

I hope your holidays go well.
