Can you not buy more than 18 beers in the same box in Texas?
He's lucky he can buy beer where he lives...........at least that's the way it was in the old day (70's)
TX used to have a lot of dry counties, not sure if they still do. And "Blue Laws" where you couldn't buy booze of any type on Sundays even in a wet county/city.
But Roger can explain it better about the 18 packs.
