This is a 60% saving, so you might need to be quick. While stocks last and all that. WH Smith has reduced the price of the Hama Rally 4000 Piece Midi Set from £14.99 to £5.99. However, to get the best saving you'll need to be able to collect for free instore. Otherwise the lowest cost delivery is Saver, at £2.24.
I'm really intrigued by these bead sets. They look like a lot of fun to do, especially for children like my son who doesn't get into any sort of craft work that involves drawing or colouring in. WH Smith doesn't say what you get in the box; the site simply describes it as a "colourful arts and crafts game will have the kids amused for hours. Choose from one of the many car designs and get to work with your beads to create your very own."
However I did find some information elsewhere on the web. Apparantly this set comes with 4000 midi beads, two interlocking square boards, stands, ironing paper, designs and instructions. Do keep in mind that this is not stated on the WH Smith site. It is recommended for ages 5 and up.
