One of my son's favourite Lego sets is on sale for £16.74 at Amazon. Normal price is £19.99 (or extremely close to it) at most retailers so you get about a 15% discount and free delivery.
This is pretty good for younger Lego lovers because it is robust and quite easy to build. Comes with Anakin and R2D2 figures.
This kind of discount is unusual for the cheaper Lego sets. Great for birthday presents.
