Once Again Not Delivered on Time

Once again USPS did not deliver my Amazon package on time with the notification left to Amazon that there was no one available. No one available? There was/is no required signature for the package! 

If I we didn’t order enough to more than cover the cost of Prime, and not use the other benefits of Prime, I would cancel it. 

I wish there was a way in Prime to designate who delivers your packages or a way to see which service the seller is using. I would only choose FedEx at this point.
