For DD, I've always done the whole "one thing you want, one thing you need, one thing to wear, one thing to read" which usually ends up being a couple of hundred although I don't really set a hard budget for it and that's what DP and I are continuing with this year. She gets so much anyway as she is the only grandchild on both sides and also has step-grandparents. Me and DP aren't doing gifts, we are going to have a super extravagent date night instead.

Parents and siblings we spend about $50 each, other family I give a $5-10 donation gift (and family knows that instead of gifts, they can donate in my honor to the Australian Marine Conservation Society), there aren't any other children in the next generation yet so all adults.

Me and my friends don't buy eachother gifts, we all go out somewhere nice for dinner instead.
