|You cannot change the LOGIN e-mail that you first made your account under. If you get a new e-mail address please do not make another account, you will lose your order history and wishlist, etc.
Rather, login with your original e-mail address, and go to:
My Account > E-mail & Password > Contact e-mail
This will change the e-mail address that we use to correspond with you, send order receipts, etc.
So basically your LOGIN e-mail will always need to be the e-mail address you first used when you made your account.
