I have been to certifit once and will never return.
They have employees that have zero knowledge on what they are selling. I speak of the one in Raleigh, NC as I'm sure Employees are diffrent in other locations and stores. I can see why the Raleigh Employees are incompetent, because they are lead by some Guy named Mario, that's brain power is equivalent to that of a laboratory Monkey. They sale you parts and expect you to make sure it fits before you leave, or you'll be stuck with it because of their inability to read or work a computer to access and or cross refrence the correct inventory part.
