Starting a thread as need some new ideas for my Y6 & Y9 boys and thought I'd also share some things they've liked up to now
Fishing Guidebook - both boys love fishing and watching Fish with Carl on YT - his book has been a huge hit and I ended up buying them as cousins gifts too. It's one of the few books my two have read without a fight.
Noodles advent calendar - UPF bonanza - but my eldest loves this last year
Y6 desperate for a "farming simulator steering wheel" this year - which I hope will be a Black Friday thing 
Then I'm on to just updates of what they have - Y9 just grunts when I ask him (could just go with that and not bother at all?)
