The 3 cube sets are usually around the £10 mark but Amazon have "Jobs" and "Animals" and "Sports" on offer right now, with the price starting from £4.77.

Geomag Magnetic Cubes
There are also bigger versions of these, 6 and 9 cubes etc but I'd start with the reduced ones and see how your little one gets on with them before shelling out!
Delivery is, as always, fast and free if you have prime.
