          I was hoping to have item shipped faster to store based on information provided on website. This was not the case. Product arrived at store same time as arrival at house.

          Exactly what I needed, Home Depot needs to learn and understand what to stock in the stores. I worked for them for about 10 years as a Master Electrical Specialist and it was a constant problem to stock the proper items that are REQUIRED by the National Electrical Code.
