They ship USPS so I don't know how they get shit to you that fast. I ordered a book the other day that was shipped from Washington state which is on the other side of the country from me and shipping estimate was like 4 days at the earliest. I got it two days later with normal standard shipping. USPS must be stepping their game up so they don't get shut down. I've experienced this now multiple times that amazon gets shit to you days earlier than they say. I realize what they're doing with that, it's to pleasantly surprise your already lowered expectations. But honestly, expedited shipping is useless cause it's there on the second day even if it's coming from across the country. School book that came from one state over were there the next day, all reg shipping.
