My mom never gave gifts to my brother and me - everything was from Santa. So that's the way I do it, too!!! I am probably an "overboard" shopper, but I don't care. Everyone gets to do what they want for their own children.
I'm more of a "category" shopper than an "amount" shopper. Santa always brings one big gift (electric
scooter, Ipod, pair of designer jeans, etc.) that's probably in the $100 plus dollar category. I fill other requests within reason. Last year, DD16 wanted the jeans, a special pocketbook, and some boots. So those were her "big" presents. Younger DD got an equivalent gift for each of those, although hers cost much less. Boy, do I miss the days when $25.00 could buy you enough Fisher-Price to fill the space under the Christmas tree!!!!
Then I always add the other categories - new hardback books, DVDs, CDs, board games, and art supplies or craft kits. These are things that haven't appeared on anyone's list, but are surprises nevertheless, and although they may not all be played with right away, they are great gifts for the long winter and spring. These numbers are fluid - for example, sometimes I won't be able to find any DVDs that we would like, but other years there might be three or four that have come out. Same with art kits or CDs (although I can always find good new books!!!)
So we have a lot of packages!
