For those that don't know: If your B&Q store has a timber cutting service, then they will cut it for you free of charge. It used to be just 4 cuts but now it is up to 15 cuts for free. This is a big help when buying the large 8'x4' sheets of wood which is often cheaper than the smaller sheets and fitting it in the car. I often use it for splitting up MDF sheets when I don't have the ventilation.
They do appreciate a good cutting diagram which accommodates the 3mm kerf of the blade before you wander up to the machine. Of course, this does rely on their cutting service working and a qualified operator being around. Sometimes they have a bell you can ring!
