this is a hard one to answer knowing nothing about them LOL

I’ve had to find several gifts for that age too. I chose a huge beach towel, a pocket torch (but mobiles have torch apps in them I’ve since been told), a biro that has small screwdrivers inside it and a thriller novel. You can get some good ideas looking around Jaycar (a bit like Think Geek) where they have gimmicky, fun things. Happy shopping.

It really depends on what they are like.
I have a nephew who loves books and nerdy stuff. So books and videos of Avengers, Guardians of the Galaxy, IronMan etc also games for whatever console they use. Minecraft is a good one. There are both books and games for that as well as numerous toy type items. Go to a Popculture store. They have loads of stuff suitable for them.

Stocking stuffers, I got a heap of them collector cards they have all sorts, I also grabbed a few of them lego mini figurines cheap and effective I filled the stockings with ease.

Any sport related stuff, clothes or gift vouchers for buying games of their own choices.

Check out websites in your state Groupon, Scoopon, Living Social, Cudo. We got a great present earlier this yr a Paintball Experience for 8 for under $50. Zoos have Animal Adoption or Behind the Scene Animal Experiences as another idea. In Adelaide I can get gift cards at the supermarket for AMF Bowling/Laser Skirmish.

Any games for there consoles. Vouchers for time zones, trampoline centres. Outdoor sporting equipment, skateboard . Money so they can spend on school holidays
