I had no idea that Amazon was doing Sunday deliveries, until I started seeing my packages marked 'unable to be delivered' on Sundays. This seems like a lot of extra effort to go to and not inform the customer that you're doing it.<p>It's also pointless. My mail goes to a mail receiving shop, and none of these places are open on Sundays because there's never been any mail to receive. A lot of people around here have their mail sent to their office, which similarly are not open on Sunday.<p>Even if I received my mail at home, I have no expectation of it arriving on a Sunday. The chances of being home to receive it are very slim.<p>Seems like a lot of unnecessary effort and misplaced priorities. I'm fine with waiting until Monday, and that's the result anyway.
