Can I delete credit card from Gamestop without cancelling order?

I pre ordered Assassin's Creed Revelations from Gamestop with my Debit Card which right now I don't have access to it for personal reasons. I checked my credit card status and there was a payment from Gamestop which is still pending. If I go to my Gamestop account and delete the credit card information, will it also cancel the order? I am still going to buy the game but with cash instead of credit/debit card.|||It shouldnt cancel it, just make sure you dont cancel it, lol.
