If there's one toy that children and parents love, it's LEGO. Ok, so it might not be as much fun if you stand on a piece at six in the morning, but building a cool LEGO creation is something parents and children can share together. But with prices coming in at anywhere up to hundreds of pounds, it can be an expensive hobby. Luckily, Amazon has brought the price of LEGO tumbling down, letting you save on the latest builds or the set your little one has had their eye on.
