$3.89 the cheapest, $4.09 at the brand name stations. We have a chain here, Terrible Herbst that gives something away everytime you buy gas. They always give a free fountain drink or a cup of coffee. And every month they give away different brand name products. This month a Free Monster Energy drink, and a liter bottle of Dasani water. Early in the month I will get some gas to see what the freebies are.
There are 2 stations here, 1 in the middle of town the other close to my house. Grocery store is right by the one, so if it's something I like I will put $10 on one card get the freebies. Then stop at the other one by the house, put some more gas in on another card.
