Using either padded flat rate envelope or medium flat rate box, the rate would be approx 9 to 15 with USPS Priority.

I too am confused. I'm used to USPS where if you want to use a Priority box, you buy priority postage. If you want to use Flat Rate you use the Flat Rate box or envelope.

Went to a FedEx store and was told that the package didn't have to say OneRate on it -- just FedEx and be the right size. They had white and brown FedEx boxes and while poly mailers available.

2 orders today Amazon blocked shipping on USPS ground AND on USPS Flat rate envelope. The 2nd flat rate priority was estimated FL to MD 7 days! This was 2 days longer than ground and definitely incorrect. There seems to be a bug in the estimates, almost like ground and priority mail are switched. Order 111-3765292-3912204
