Double holy hell. I just got back from picking up a burger in town. $3.86 yesterday. $4.16 today. I'm glad I filled up yesterday.
*expletive deleted*ck you, Brandon!
Edit: Interesting - I was just looking at Gasbuddy and the Costco closest to me, one hour ago was at $3.68. Another Costco maybe 10 miles from that one, 36 minutes ago was at $3.78. I would assume that Costcos that close to each other would have the same pricing, so this is all changing very rapidly.
