I'm trying to spend less than last year. So, both kids will get roughly $200 each spent on them. I'll spend ~ $75 on my husband, ~ $50 on my mom. We may splurge and get the kids a PS2, but I'm kinda waiting to see what it gets bundled with, gamewise, before Christmas.
My 5yo is done except for a couple of hotwheel cars and play-doh stocking stuffers. This shouldn't be more than $10. My teenager actually went with me to pick out her gifts. I still have ~100 to spend on her but if we get the PS2, I'll get her some games. She may get a BB gift card to round things out.
My kids also exchange with 2 of their cousins but we have a $20 limit. Since they are a teenager and a 20-something college student we usually go the gift card/cash route with them.
Oh, I almost forgot the teenager's boyfriend. We got some pretty good deals on "Family Guy" dvds. I've spent ~$25 on him.
