I live in Boston. I seem to be getting most things in around 5 days, even though Amazon estimates 2 weeks. Almost everything was delivered before their estimates. But everything is still slower than usual (normally, I'd get things delivered in 1 to 3 days)
Probably depends on the item. I'm outside of Boston and I don't think any order has taken longer than 2 days--other than a couple I picked delayed shipping in exchange for a digital credit. (And even those arrived on the early side of their estimate.)
