USPS Express mail claims to be an overnight sevice.And they charge plenty for it.I had a package shipped express on a Thursday morning early.It was posted in California and did not receive until Monday afternoon.Thats 4 and a half days.! I will never use USPS express again USPS is terrible to begin with.But to deliver an overnight package in 4 and a half days is ridiculous.That is the speed of regular mail.What a joke...
