The bracket on the back of the spine shelf was crooked by about 3/8" of an inch so my husband had to take it off and get it straight so that the shelf would hang properly.  Also, you keep sending coupons for 10% off (first order only).  Don't send those to us who have already purchased items.  It would be nice to get a coupon for repeat customers.  I am pleased with my shelf now that my husband go the hardware corrected for hanging.  thank you.
