Warning! Fake US Bank emails
Be aware, there are fake infected emails alledgedly from US Bank Online circulating currently. These falsely claim, that "your credit-based card account was billed at Apple Online Store for" a few thousand dollars! Of course, they are NOT from Apple and have no connection to Apple and no connection to any genuine US Bank!
One I have received was sent from usbank {at} stjamesmac {dot} com and had a subject of "Apple Alert Regarding Your Recent Order" and a link to "Get Your Receipt" which actually links to a self-executing file hosted at chiropracticlibrary {dot} com. Various grammatical errors in the body of the email give it away that this is a scam and the aim of the fake email is to scare people into clicking the link which will infect their computer with malware, possibly even encrypting your files causing you loss of data.
As ever, never click a link in an unexpected email, especially one that you are not expecting nor from a firm you've never heard, these days, it'll be an attempt to scam you or infect your computer.
