The clause, which only affected customers placing orders on April 1st, still appears in the site's Terms & Conditions, apparently as a warning to those who skip the fine print:
? By placing an order via this web site on the first day of the fourth month of the year 2010 Anno Domini, you agree to grant Us a non transferable option to claim, for now and for ever more, your immortal soul. Should We wish to exercise this option, you agree to surrender your immortal soul, and any claim you may have on it, within 5 (five) working days of receiving written notification from gamesation.co.uk or one of its duly authorised minions. We reserve the right to serve such notice in 6 (six) foot high letters of fire, however we can accept no liability for any loss or damage caused by such an act. If you a) do not believe you have an immortal soul, b) have already given it to another party, or c) do not wish to grant Us such a license, please click the link below to nullify this sub-clause and proceed with your transaction. ?
If you've inadvertently damned yourself, don't worry. GameStation now says it has no plans to enforce the clause and will nullify it for all customers. Wish we could say the same about those credit card companies.
