I never really keep tracked of it.

I buy a present for Dad. My brother and I do not exchange gifts. I get a few odd things here and there for 3 or 4 friends and mail those out; and they mail me presents. Dad isn't able to go out and buy gifts. And I plan a nice dinner for the 3 of us. Maybe $200 total? Not typical, I am sure of that.
I really don't need to buy decorations at this point. Once I bought my house, Dad let me bring all the things form his house; all the things we grew up with. Plus I have what I acquired in 15 years of apartment living. So maybe a little bit for the extra lights that's it.
