I keep reading people posting that if you are planning on paying in full for the iPhone X preorder, to call your credit card company and let them know to expect a large transaction. Is this really necessary? I'm not even sure when I would tell them to expect it, since I've heard mixed reports as to when Apple actually charges your card. Some people say it happens on the 27th when you place the preorder, others say it happens when it ships.
Thoughts?
