In this case, the contract provision would be the email that amazon sends showing the date that your purchase must be delivered.
Explanation:
A contract provision is a type of contract that provides a date for when a service is to be completed and holds the person who issued the contract responsible for the problems that delaying service delivery can cause.
When you buy something on Amazon, you receive an invoice that is the proof of your purchase. However, you also receive an email from Amazon that guarantees that your product will be delivered by a certain date. In the case of the question above, this email would be the contract provision that would hold Amazon responsible for the problems that the delay in delivering your purchase caused.
