When my son lived in New Jersey I used to love WaWa coffee.
In MA when we lived there I went to Cumberland Farms. Their coffee was very good and it was $0.99 for any size. Post Covid that went up to $1.30 no matter what size. The last time we were back there in September of 2024, it was still good buy they priced by the size of the cup and it was just a bit cheaper than Dunkin Donuts. It was still better tasting, though.
Now in central Texas it usually comes down to QT, although some H-E-B gas stations have convenience stores built in. That coffee is pretty good. The problem with both is that I'm not a fan of those quick brew machines. Circle K is the worst.
