I'm a Prime member, but I have become increasingly
frustrated with Amazon's use of FedEx-Post shipping where FedEx hands it off to your local USPS who in turn delivers it. I live in a small community and work in another town. Often, my post office will leave a note to come pick up the package instead of just leaving it. They are only open limited hours when I cannot get there during the week and are only open from 8:00-10:00 AM on Saturdays. I am a Prime member primarily to get the free two day shipping. With the move to the FedEx-Post, I rarely receive my packages in the two day window. Of course, it counts as two-day with Amazon, because the post office counts leaving the note as a delivery attempt.
It's making me seriously reconsider the value of my Prime membership.
