4 year old party gift ideas

[BergamotMouse]

We have a few birthday parties coming up and I need ideas on what presents are good for 4 year old boys? If you've had a party recently what have been the best gifts?

Ideally available from Amazon, between £5 and £7 probably (as we have loads coming up)

Thanks

Orchard Toys games
Crayola twistables (you can get a pack of 24 with your budget)
Melissa and Doug reusable stickers

The reusable sticker books look great! Just what I needed to be told. And can get 3 for £15!

My almost 4 year old boy (and most others I have met!) love any vehicle. Even if they already have 100 of the same. Particularly hot wheels cars or metal die cast ones. Or ones that make annoying noises.

This should be good: Take-apart dinosaur toy and is on special offer at the moment. My son has some like it and loves them.
