Gift for 2 boys aged 7 and 9?

[superdeeduper]

I would like to buy a gift for my cousin's 2 stepchildren who are 7 and 9. I know they both like lego but don't know what they already have so quite tricky buying any sets. They also like Minecraft and Adventure Time. Can anyone suggest something as I'm stuck. Was thinking of spending between £10-20 on each of them.

The Minecraft blockopedia book is half-price at £14 on Amazon. It's got 5* reviews & is just out so they won't already have it. DS age 10 getting it.

For the younger one there are Lego games such as Lava dragon which are good.

Minecraft papercraft sets?

My DSs are 6 and 8, they genuinely don't mind receiving the same Lego set twice, the eldest is just getting into Lego Technic. There are Lego Minecraft sets. Or what about a generic lego box to share for example or a box of wheels etc.

They also both enjoy hexbugs.

Or, Minecraft hoodie, T-shirt or hat - they have them in Sainsbury's atm.

I second the Blockapedia. I received mine today from Amazon for Ds1, and it's beautifully presented. A must for any die hard fan of minecraft.

Great suggestions, thanks everyone x
