Used to? Hell, in Texas, you cannot buy alcohol until after noon on Sundays. Still. Today, er, yesterday, but you get the point.
Liquor stores (which also sell beer/wine) are not allowed to be open on Sunday, period.
Note this pertains to off-premise (i.e., stores, not bars) only. Bars, you're free to get sloshed to your hearts desire on any type of alcohol and as early as 10AM on Sundays.
During certain hours (such as, past 8PM on weekends), groceries are only allowed 4 employees. Which is almost impossible in those very large groceries. For many groceries, they just assume this is part of doing business, they would rather pay the fine than angering customers with long lines.

Blue laws around vices (specifically around the sale of alcohol) are still commonplace in the US.
However, Bergen County, NJ, still has the rare Sunday blue law that applies to everyday consumer goods -- you can purchase food and medicine on Sunday (and even alcohol after noon, per a state-wide vice blue law), but everything else is prohibited. If you visit a big-box store like a Costco or Walmart that sells both food and goods, large swaths of the store will be closed down on Sunday.

It used to be heavily regulated in Canada (or at least Manitoba) until very recently as well, like some time in the last 20 years or so. I remember when Wal-Mart first entered Canada, they had a really hard time in some places because labor laws and blue laws prevented them from being open 24/7.
