I ordered my family pack on 10/28 and it was delivered on 10/30. That was using the Super Saver shipping. I got an e-mail on 10/30 stating that the order had shipped and was really surprised when I got home from work to see that it had been delivered already. My order notification said that the estimated deliver was 11/15.
Ordered from Amazon 1.5 weeks ago. It was shipped on Monday, and it arrived on Wednesday. I installed it yesterday (archive & install) without a hitch. Lot's of speed improvement, but Leopard is not earth shattering. You can probably wait it out.
