7.5 You must wait a minimum of four working days before reporting a disc as not received or lost on the way back to us. It is your responsibility to then report all lost discs online. We are unable to offer a refund for any discs which are paid for by you and then found at a later date. You must comply with either Royal Mail's claim compensation process or our process. Failure to comply with these processes, as amended from time to time, will result in a charge being made for the lost disc. The current charges are £10 per lost DVD, £17.50 per lost Blu-ray or HD DVD disc and £25 per lost game.
i wouldnt do it with DVD, blu-ray or HD dvd but think about PS3 games they cost 39.99 in the shops.
Dont post the game wait for 4 days and report the disc lost or stolen ( stated in 7.5 first line)
