Super Eggsaver used to sometimes take over a week to arrive, but lately I've noticed faster delivery, typically about four or five calendar days. Don't quote me because I have not made a careful study of these delivery times.
If I don't need it in a hurry then I use it, which is most of the time (if it's available). Why pay for faster shipping if I really don't care when it's delivered? You have to trade off the excitement of a new build with whether you can afford to pay for faster shipping. If you can be patient, save the money and wait, otherwise pay extra and get it sooner.
