I don't think it's tacky.

This year I can only buy for the children. When anyone else asks what I want, I say I don't want anything (which is the truth, I can't think of a single thing I'd like to have, exept maybe some socks and undies)

This year I just want some peace and happiness.

With the economy the way it is, it should be expected that people will have to cut back this year.
