In Alabama, all liquor stores must buy there booze from a "state store" - this includes restaurants and bars too. The kicker is that these state stores are open to the public - anyone can buy booze there at a deep discount, but most of them are only open from say 9 to 5. Liquor stores have to buy at their cost - mark it up - and stay open all night to sell to the drunks. I think you can make a living at it, but it is far from a slam dunk IMO.
