Killer prices! And because of that sometimes there's bigger lines but even then they move way fast. Usually you don't even need assistance but if you do the staff there are usually pretty accessable and friendly.
WARNING: You must have a Sam's Club card to buy gas here.
What I like about it is you can get gas and then everything else you need. With it being right off state street it's easy to get to no matter what time of year it is.
