Costco of course is consistently 30 cents cheaper than regular stations, more than that for premium. Among regular stations around here, anything near the freeway adds another 30 cents or so to their prices. Normal station prices here are just under $3 for regular. Costco was cheaper than I expected this time. They don't bump their prices until the next load comes in. But there is a line, usually, a few minutes of waiting.
Their wine prices here are 2/3rds what they were in Cincy, even at Costco up there.
