This is the note at check out: "You will be authorizing a few cents at this time that will not be charged. For fraud purposes, we may ask you to check your credit card account and let us know the amount you see. The full authorization will only occur after we verify availability and that no other parts are required (if there are any, we will contact you). If this is for an installation, the full amount will be authorized the morning of the installation and the funds will be captured the following day."
