The box was mostly destroyed when it was dropped off at my house.  I had no choice but to carry in each piece one by one from my driveway.  The delivery team would have had to notice this as the box was not able to be picked up at all.  But no note or anything, just a pile of cardboard and metal.

I was able to assemble the shelf, but several of the corner posts were warped, potentially from whatever ripped the box during shipping, and had to be bent to fit together...far from ideal.  It might be better to buy something like this from your local big box store.
