I started buying milk in a bag when my oldest daughter was born, and that was in 1990. We don't have two of anything in our nearby town, but we do have two Kwik Trip stores. They have always carried bagged milk & more recently orange juice. There are over 800+ stores in Wisconsin, Minnesota, and Iowa (called Kwik Star there).
They buy milk from dairy farmers within 100 miles of La Crosse, Wisconsin, & ship out 90,000 gallons of milk per day. You can buy their milk in plastic jugs, too. They also provide plastic pitchers for free. The milk bags slip into the pitcher, and you just snip the corner of the bag to pour. They process the milk the day it's received, & I have noticed over the years it will keep for much longer than milk bought elsewhere (like Walmart).

I traveled through Wisconsin, Illinois, Indiana, Ohio, Connecticut, Massachusetts, & New York the past three days with my Mirage (approximately 2,300 miles). Kwik Trip in Wisconsin is my favorite place to stop for gas by far. Their food products are always fresh, priced low, and usually well-stocked. I buy all of my milk, eggs, bread, orange, & sometimes things like potatoes. Their angus cheese burgers are awesome, but they offer a variety of healthy food, too. I am not as impressed with other places that I stop at in other states. Kwik Trips are busier than McDonalds or other fast food places during lunch time in my area.
Kwik Trip also offers a reward card that gives you a discount on everything including gas. For the past 30 years, I have had their Kwik Trip rewards credit card with a $1,000 limit.
The milk in the bag discussion has come up before. It's been in my area for decades. I didn't realize it was a novelty thing.
