Since your order is comprised of multiple packages, all of the boxes may not all arrive at the same time. We've seen 2 boxes arrive early and the remainder arrive on time or 1 boxes arrive on time and the 2nd and 3rd box a day behind which if the first delivery happens on Friday, the remaining packages may not arrive until Monday or Tuesday. Since we ship via UPS, we are beholden to them so we can't offer any guarantees of the arrival or if all the packages will arrive at the same time.
