does fedex service saver only ship at 7 pm on weeknights?

Answer 1

if you are talking about fedex express saver
and you dropped your package off at a Fedex shipping locations
all the packages are picked up at the same time and then
are taken to the hub for sorting, if a package is designated
super saver it will make the same trip as the regular packages
to, it just is held back at the destination location
and will still be deliver by the 3rd day (sometime it will be delivered
on the 2nd day
