The SKMutablePayment class defines a request to the Apple App Store to process payment for additional functionality offered by your application. A payment encapsulates a string that identifies a particular product and the quantity of that item the user would like to purchase.
When a mutable payment is added to the payment queue, the payment queue copies the contents into an immutable request before queueing the request. Your application can safely change the contents of the mutable payment object.
