Twin 9 year old daughters here (they will be 10 in February). I have one girly girl and one not so girly but not quite a tom boy. Some of the current favorites are Minecraft,
Lego Friends, and the Hunger Games. Dolls are a thing of the past. I usually don't but clothing as Christmas gifts unless it is something themed or outside of my normal clothing/shoe price range. Thanks to this thread I will be purchasing the rainbow loom soon.
I've purchased the following so far:
Disney Infinity plus additional figurines (this is more of a family gift)
Lego Friends Dolphin Cruiser and a few smaller sets
Minecraft Lego sets
Minecraft creeper hoodies
Minecraft T shirts
Hunger games T shirts
Nerf Rebelle Crossbow
Arts and craft kits from Michael's (they currently have a coupon for 25% off and sale items are included)
Kingdom Keepers book series
Ipod touch and Ipad mini silicone cases in fun shapes (puppy, monkey, minion)
Itunes gift cards
Digital watches with silicone bands
Alarm clock that projects the time on the ceiling
Mini remote control cars
