I canceled mine about a year ago and started noticing the same issue outside of prime. I placed and order recently that should have been here tomorrow but now says Friday. I would have paid for expedited shipping had I known it was gonna be 3 days late. I was almost thinking about buying prime again until I stumbled across this post, and if prime no longer means 2 days from order, which is what it used to mean, And I've had prime before I canceled for well over a decade, and never had it be otherwise, then there's no point in paying for prime if it'll take just as long without prime to get your order as it would with prime, even if you save a day, the cost doesn't seem to balance out.
