This mistake cost me $800 on a flagstone patio project

I purchsed 3 tons of Flagstone for a patio project and this mistake cost me $800. You can't tell by this quick video, but the stones were filled with major humps and dips. The dips are so large they can hold water like a plate. So I had to go back to the drawing board and purchase more stone that was specific for flagstone patios costing another $1000 for the Tennesee Flagstone. I'm happy with the end results.
