Great place and well worth the drive if you are coming over the border from NC. Have used Frugals many times, usually when I need larger than normal amounts of alcohol. Parties...weddings...etc... I have used their keg service which is very reasonable price wise, borrow a tap from a friend, don't let them rope you in on tap rental!
As other have said, its split into 2 "sides", one for beer & wine, the other for liquor. Every employee I have dealt with have always been super nice, and helpful. The store is very clean, and easy to find what you are looking for. In the rare occurrence they don't have what you are looking for they have offered to place orders for items they don't normally carry. This is my go to spot when I am near the SC border, and again i'll echo other reviews, grab some cheap SC gas while there!!!
