Johnstone Supply at 3895 Grove Avenue, Gurnee, Illinois.

First timing going to this location and I was very thankful for the service. I showed up 38 minutes before store opening (not knowing they open at 7:30) and a minute later the lights came on and the door was unlocked for me. He willingly worked with me despite not having an account with this branch, ran the credit card and I was on my way. Friendly and cheerful, something everyone appreciates. I would go back here.
