We always just buy for kids, our own neices and nephews. and we dont spend much.
With the adults a few years back we started a "Crap KK" tradition. Everyone brings one gift, the cheapest, ugliest, crappiest thing you can find. We then get pull out a number whoever has number 1 picks a gift, then number 2 opens one and can decide to keep there own or swap with a prior opened one and on it goes. Its heaps fun everyone gets a laugh and sometimes what one person thinks is crap another thinks is great.
Christmas for us isnt about gifts, we prefer just getting together with the people we care about. We have huge lunch and everyone brings something to contribute to the meal or drinks.
Df and i dont buy each other gifts either.
