I've just been panicking about what to buy my 7 year old ds for his birthday - and we went to Tesco, where we saw a Cranium mega fort building kit (you make your own playhouses in all sorts of shapes). It was advertised as a special offer at £31.93, which seemed reasonable, so we got it. Anyway, it went through the till at £19.99!! Just thought I'd share that with you all as it seemed amazing value and looks like a brilliant toy.
I can confirm the *CRANUIM MEGA FORT* is a superb buy and great value too. My 4yr old received one for his birthday and it has been a brilliant game especially as the weather is soooo poor at the moment. We builda nd then rebuild new exciting tents, dens, hide aways and he spends hours in there playing. A great one to teach logic maths all sorts of things through play. Word of warning....it is big!! You need a large room if using indoors, weather permitting its a great garden toy too.
