What day was it "accepted" by them? I am tracking a few things right now. Shipping label was created on 6/12. USPS didn't accept until 6/15.
Their service is usually horrible. I once had something "out for delivery", it didn't show which isn't odd, as I was heading to bed I decided to track it to see if there was a note or reason for not dropping. Status had switched from "out for delivery" to "arrived at USPS Burlington, NJ". I live in Delaware, the status before "out for delivery" was "arrived at USPS Wilmington, DE" which is a 3 minute rive from my house.
