What size box does the eGranary ship in?

We have three standard box sizes at our disposal. For single internal and external eGranaries, they ship in boxes measuring 12x12x8 inches. For servers, they ship in boxes that are 24x20x12 inches. For orders of multiple eGranaries, the box size will vary depending on how many and which type(s) of eGranaries are ordered. We make an effort to use the smallest box size and the least number of boxes. The largest box we may go with is 20x20x20 inches. All boxes are double-wall for added protection.
