I am not for sure, but I think that if it has not shipped, you can cancel it and start over, but I am not sure that you can modify an existing order. I have never tried anyway, but they have always said that I can cancel if it has not shipped.
If they are like most online sales venues you should be able to call them up. They can probably alter the order for your right over the phone or delete it.
