Yes and no. "Announced" and "Shipping" (and "Available for Rental Reservations") tend to be three different dates. Regardless, LensRentals.com is running a Black Friday sale for a few days where we can make two reservations for any ship date at 25% off. I think I can drop items out of a reservation, but I can't add others in after the fact.
