It's a bad week to be shipping anything this week with a large damaging storm affecting the east and south. With so much disruption in traffic, ground and air, I am not surprised they are delayed. The grow gel will help.
As for Priority vs Express shipping, express can cost 3 times as much and does not guarantee they will arrive overnight. Sometimes Express can take up to 3 days.
