I don't see a way to update or delete billing or shipping addresses. I try not to worry about things that are likely not to happen, but I can see this coming up sooner or later, say a college student that moves each year or something.
Or what if you change email addresses? You would have to add a new address just to change your email address?
I searched the forums for My Account and Billing Address but didn't find anything that looked related to this. Surely someone must have some feedback on this.
Thanks.
