I live in Missouri and you can buy anything in any store, comer convenience store, walmart, any grocery store, any day any time, wine, beer, liqueur
Loved it when I was down there. Went to college outside of St. Louis. We even bought liquor at like 1 am in Illinois (grocery store). I like that part of the country lol.
Now that I live in MN, I have to make sure I'm set for football Sundays by Saturday. Only once have I had to go to a grocery store to buy some 3.2% beer on a Sunday, since that's all you can get on Sundays.
