I was satisfied with he book shelf but upon assembly I was short 1 screws and contacting wayfair I was told to send it back and they will replace unit but all this for 1 screw I decided to purchase a replacement screw at the local hardware store. The time and effort to disassemble the bookcase call UPS for pickup and wait for replacement was a bit much.Could you not send me 1 screw instead.  Thank you.
