Using the posted vouchers for Marshall ward, if you add the play and charge kit and then add any other cheap item, then at checkout add the attached £15 off voucher, it comes up to a total of 5.50 including delivery. and you can get in black and white.
This could also be used to get £15 off and free delivery on any of the other xbox 360 stuff on offer.
Ok to do this you need to add another item , find the cheapest item you cna find, and use only the £15 off voucher, will come to around £5.50 or less if you find a cheaper item then i did.
//Edit it is actually possible to get it free afterall, whether they honour it or not is uncertain. all you need to do is copy the link for the next part of checkout and then paste it once it is in basket with vouchers - credit to deathtrap3000 for figuring out how to get past the no continue button
