Majority of mine, until Covid, was 2nd day as they promised. I'd order on a Tues and have it Thurs for example. Maybe distribution location?I have never gotten any Prime package delivered in less that three days, and that's over the past decade to three different addresses. It used to pretty much always be three days, then last year it jumped to around four days on average. Haven't ordered anything from Amazon since September, but it was around 5 days then.
