If PCD contacts you/dealer to confirm dates, and you decline all offered dates, they route the car to the dealer at no cost.
If you (or the dealer) confirm a PCD date, the car is routed to the PCD post production. If you need to cancel after confirming the date (unless, maybe, it's like, fairly immediately after) you would be responsible for shipping costs from the PCD to the dealer.
Edit: BTW, I also seem to recall that there is a six week window from when the PC initially extends the first date of delivery. My most recent PCD sat at the PC exactly six weeks prior to our arrival.
