Delta Sonic is where I usually gas up. The prices seem to be consistently a bit lower than the other gas stations in the area. I always pay at the pump, so I can't really comment on their convenience store type items. You don't want to go here around 5:00pm on a weekday, because the wait can be really long. I'm also not crazy about the layout of this particular station because occasionally people in front of you will block you in, and the exit/entrance are a bit inconvenient. Overall though, its is the cheapest gas on my way to/from work.
