Package stores and other retail sellers of alcohol, including groceries and supermarkets, would have the option to sell on Sundays and major holidays like Memorial Day and the Fourth of July, in a legislative attempt to compete with neighboring states. […] Expanded consumer purchases are expected to bring in a modest $5.2 million a year in additional tax revenue, when Connecticut leaves Indiana as the last state without Sunday retails sales of alcoholic beverages.
UPDATE: Article appears to be incorrect with that declaration. Added Minnesota and D.C. which apparently forbid Sunday retail sales outright as well. Several states have soft bans or strict measures around Sunday sales.
