When I ordered my phone, the $5 auto-reboost discount was still in effect. When I activated my phone (on 8/22/17) the discount offer still showed on the payment page, and I set up auto-reboost at that time. Now, several days later, I discover that the credit will not be applied, even though the offer was clearly on the screen at the time I set up the auto-renewal payment. If it hadn't been, I would have questioned it at that moment.
