I tried to add it under Credit Card under My Profile.
Where do I find the Limit option?
I bought a gift account using my name and address (real) since it had to charge my real credit card and sent it to another email address. Don't remember what I put for name or address. How do I change?
Yeah you should have put the stealth account info as the recevier. It probably won't work but you can try it. Go to View Limits, it is on the main page after you log in.
