What an awful, prohibition-warped system.
In the end, the eastern state sold me more liquor at lower prices until I realized that I was drinking too much and quit. Everyone I knew back west drank; few do out east.
I used to live there and the only place to buy 6 packs was at a restaurant that also served food. They've since loosened up the beer laws, allowing grocery stores and convenience stores to sell beer as long as they have fresh food available and tables for dining.
