I'm fairly certain that supermarkets and gas stations still sell 3.2 beer. 

Interesting fact: "3.2 beer" means that the beer contains 3.2% alcohol by weight. The percentage you normally see on beers at the liquor store is alcohol by volume. If you measure 3.2 beer by volume, it's about 4%, which is the same as a lot of regular beers like MGD and Bud Light. So 3.2 beer isn't nearly as weak as most people believe it is.

This makes the law even stupider when you think about it. Why is it legal to buy a case of 4% ABV beer but not a 6-pack of 5%?

I think the entire internet should be shut down on Sundays so that we don't have to moderate PDD seven days a week. Sundays are for church anyway. You shouldn't be using the internet on Sundays.

According to this article, 3.2 beer is literally just slightly watered down. Something else to consider is that extreme low-calorie  beers like MGD 64 also have far less alcohol than 3.2 beer. I haven't checked, but I would bet that supermarkets sell those beers.

According to this recent report by NPR, "While many states have laws restricting liquor sales, Indiana is the only one where you can't buy packaged beer, wine and liquor on Sundays." Hm. Maybe they should fact-check a little more thoroughly?
