I ordered two of these shelves.  They came in a timely manner, but when I opened them, NEITHER came with instructions and only one of them came with the necessary screws, so I had to call customer service to get the others.  The person that I spoke with was very helpful, but it took 1.5 weeks to get the screws in the mail, while I had received the shelves 2 days after I ordered them.  Those should have been overnighted to me.
