When all the nieces and nephews turned 18 we called it quits. We told everyone we were not doing gifts. We now have grand nieces and nephews but they are still to young to know the difference. in a few years we will probably start up again.
I think once you hit a certain age Christmas is more about enjoying the season than the gifts. At a certain point you just don't need anymore "stuff".
Mrs. Doom and I usually just get things when we see them (within reason) through out the year.
When we were younger we did all of our Christmas...
