Of the few times I've been there, the staff has not provided kind service. I tried to enter once just to browse their selection and they closed the door in my face. I don't think it was time for them to close yet, either.
I have been able to buy cheap dvd's and vhs' before but I rarely visit because of the staff.
The staff doesn't acknowledge you when you enter. So don't expect to hear "Good Afternoon" when you open the door.
