I don't know if this contravenes advertising rules - apologies if it does. I don't work for them or anything, but it's astounding value for money if you're a big Martin Waddell fan like I am my son is!
The Book People have a set of Martin Waddell books for £10, including Farmer Duck, Owl Babies and The Big, Big Sea and Once there were Giants, which I didn't even know was still in print.
Fab value - DS has his 3rd Birthday in August so, at £1 a book, a few of these may be finding their way into party bags.
