However, where I live everything at gas stations is really expensive (like 3 times the super market price), because they don't make a lot of profit with gasoline. Most of their profits likely come from car services and selling stuff 24/7.
I don't know how it's in the states, but most shops here open at 7-8am and close at 7-8pm and are closed on sundays, so if you need something late at night or on sun-/holidays you drive to the gas station.
Tbh, the only things I ever buy there when every shop is closed are alcohol and tabacco (and some times paper and filters for weed)
Not too long ago I was in school and some guys had a presentation about computers in the 70s-90s they talked about magnetic data media. One of my class mates asked "what the fuck is that magnet thing" the guy answered:"it's something like DVDs for example"
32oz is about 1l and 48oz should be like 1.4l, not that far off I think
