This place is near my home so I go here a lot. It's a large store with lots of selection. Sometimes it's very difficult to find someone to help me, but when I do, they are extremely helpful. Even when a person is outside their section, they are willing to help. Recently I went there to get materials for a project and a staff member who happened to be in the lumber section but didn't actually work in it, helped me choose materials and even cut it using the big ass saw machine.
Never had any issues returning items. Cashiers are quick and friendly too.
The reason I am giving them only three stars is because of my difficulty in locating staff members.
