How long do you think it will take for my stuff to get here with Amazon Free Super Saver Shipping? I ordered a DVD and some anti-virus software and they are both sold directly from Amazon. They are being sent with USPS. I ordered them on the 5th. I tracked the order and all it says is that it arrived in Phoenix, AZ on the 6th and the electronic shipping information was received on the 8th. It says the estimated arrival date is April 13th. Do you think this is true or will it be shorter/longer?
