So I bought 6 of the 24" wide units. First they only come with two shelves so I thought I would just buy a 6 or 8 more shelves. First they don't offer extra shelves for this unit. Second they say they offer extra shelves for the 36" unit. So on Closetmaid web site it tells you where to buy. I put in my zip code and within 100 miles, no results. I then put in Phoenix AZ zip code with "No Results". I then put in Denver, CO zip code with "No Results". I then put in Atlanta GA zip code with "No Results". So the fact is they don't offer the 36" extra shelves. Is it really that difficult? ClosetMaid makes the shelves! Put two in a box and sell them separate! I will not buy another Closet Maid product. I wish Home Depot would carry another brand. I bought several units from them for my last house and they also offered extra shelves. I would return all of these but since I spent the time to assemble them all, about 45 min each, it is just too much trouble to take them back. They also are not build nearly as well as the prior brand Home Depot carried with just glue and screws compared to the interlocking metal connectors. If I could I would have given 5 negative stars.
