i used to have an app for it and would not fill up before checking it. i did always try to pick one that was both low and near where i needed to be. i wouldn't drive across town just to save $2.00.

with how high prices have been i ended up getting the app again and found out one near where i usually buy groceries is over 30 cents cheaper than ones i usually go to. ive filled up there the last couple of times. the first time i was already across town but this gas station was near my house so just stopped there on the way back. i was closer to empty by the time i got there than id like to be though.
