Less than $100. All we have to supply for the dinner is two pies, and the ingredients come out of the regular grocery budget.
I already made the cards for our relatively small card list, using stash items. Less than $5 in postage.
I bought the two nephews "like new" used books, for a total of $3, on small business Saturday. I also made a taggie doll for the three month old niece, who really has no need for a present but c'est la vie.
The husband gets a set of of four Guinness pint glasses I scored at a garage sale this summer, along with a 6 pack of said Guinness. Ordered my mom a photobook from our summer road trip, using a free Snapfish coupon that printed on the back of my grocery receipt back in October.
The kids each get a Lego blanket I knitted, handmade PJ bottoms, books from the same used sale, a Lego set each, a handmade ornament (tradition), and a few other odds and ends I picked up throughout the year. The Legos were the expensive items, but I bought them through Amazon with free shipping, and went through Ebates so I got 4% cash back.
Each year I try to spend less than the previous year. Kids don't need a lot, because of they have three sets of grandparents and two aunts that will more than make up for what we don't buy!
