The person who helped me with my project had the correct measurements, and was so wrong with what was needed for my countertop job, cost me over $700.00 extra. They will cheat & lie to make the sale. When I needed additional supplies, the store raise the price 100%, because I had to finish my project and I had no other place to go because I started the project with their product. My contractor knew they had pull a fast one on me, but there was nothing I could do. I will never step foot in that store again. From now on I will only go to Homedepot or Lowes, I have learned my leason. Watch yourself when buying supplies from this place. It may not be a good deal in the end. Trust Me!!!!
