Wow, only $2.49 for gas on September 5, 2017. If you are used to Arizona prices, this may be a little high, but there are places where gas is already almost $3.00 per gallon.
If you get here really early in the morning, you won't have to wait in line.
The only thing I don't like about Costco gas stations is that you can't wash your windshield if it is covered in squashed bugs.
There is space here for 18 cars to fill up at the same time and that can result in long lines at peak times.
