Just as a note that market I am in seems to have lots more free ONE day delivery. I don't even get why they advertise that - you used to be able to pay $3.99 or something for one day, now its free? And also in an amazon now delivery zone which goes even faster.
Amazon just did a deal for something like another 20 Boeing 767's. I'm very surprised to hear they are pulling back from 2 day / prime. My experience is they are going the other way.
