I dont order online often, but why are packages so slow?

Short staffing and stuff aside, I hardly ever order anything online. When I do its ALWAYS late. Sits at the carrier facility forever. Might as well not even use Amazon prime or order express anymore because it doesnt matter how fast something is shipped out, it ends up staying at the carrier facility here in Springfield for days, sometimes almost two weeks at a time. Is anyone else having this issue?? Amazon obviously can't do anything about it i guess, but I'm tempted to just go pick it up myself at this point. I have things I needed literally yesterday and now my whole week is messed up because of the late delivery.
