I realise this is a little early but i don't want to leave it too late and end up with no ideas.
I have a 1yo, 4yo, 14yo, 15yo and 16yo. Me and DH usually buy a couple of big presents and then a lot of small stoking fillers and a new pair of pi's for all the boys. We were thinking of ideas for the big presents this year and realised we don't have a clue what to get the teenagers. They have about every gadget going that they actually want (iPads, iPods, xbox, blu ray player, laptops, phones ect) so they don't need any of them. The older two both play sports but don't need any equipment or anything for them as they have plenty. They have access to their own money so presents like xbox vouchers and cinema vouchers would kind of be pointless.
The 14yo likes art and we found a great present for him (a custom made sketchbook/journal) but his birthday is christmas day and that is going to be a birthday present so we are back to square one.
So basically i'm really stuck and starting to panic already and its only september!
