We spend about $500 each on our kids, and probably $500 total on DH and myself (thought we buy things for ourselves that we would have bought anyway)
On my side of the family, we buy only for the 'children' (those still in high school and younger) There are 3 children in that category, two of which are mine, so I buy only for my 10yo niece. I usually spend $25-$30 on her. Then EVERYONE in the family participates in our grab bag. We do the pull the number thing and pick a gift based on our number, then trade with the already opened gifts. Since there are 4 of us, I need to buy four gifts for the grab bag...price limit is no more than $15 or so (I have 3 gifts for that so far, one cost $1, one was $12 and one was $16, need one more).
On DH side of the family, MIL is unhappy with the idea of 'not' exchanging gifts even though she is never happy about the gifts she gets, nor is she creative about the gifts she buys (adults get gift cards, kids get something about $40, usually clothes). We buy a gift for MIL, one for FIL and one for BIL, spend about $25-$30 each... MIL gets a gift card (she returns anything else), FIL and BIL get some sort of gadgety tool. I usually get her a picture or a photo book as well.
I don't do gifts outside the family except the dance teachers (4 @ $5 gift card for Dunkin Donuts each) and the mailman (again $5 Dunkin Donuts).
So outside of our immediate family, maybe $200 total.
