Microsoft has a neat promotion on the company's official store where you can pick up either the Surface Book or Surface Pro 4 and bag a free dock and pen tip kit. Prices start from £1,299 and £749, respectively. The free goodies bundled with either Surface product are worth £174.99.
The pen tip kit contains four different pieces that can alter the experience and fine tune your input. This deal ends on June 1 so you have a few weeks to decide whether or not the Surface Book or Surface Pro 4 are ideal investments for you.
