“Critically panned” means to receive a poor critical response. I tried looking for the etymology, but couldn’t find anything convincing… It seems to have started as something to do with panning for gold (i.e. using a literal pan to sift through dirt looking for gold flakes), but I can’t see where that shifted from “looking for small bits of good in mostly dirt” to “this straight up sucks”.

I use FedEx for work, and our account has heavily discounted rates for Priority services - not for Economy. That’s what I assumed was happening here, until I saw that you were dealing with them as John Q Public.
