Same here. And it's not a matter of the actual shipping taking longer. I noticed that once I stopped subscribing to Prime, my orders would wait a few days to a week before shipping and then get to me the next day.

It feels like, since I'm so close to a distribution center they can only make Prime worth my while by sitting on the packages longer unless I pay them. And probably the only time I paid extra to have something next day they botched it.
