Vallejo Costco has the best gas prices anywhere, that I can find.
They seem to be perpetually out of Kirkland cheddar cheese.
They're sourdough bread is very good and at two dollars and fifty cents a loaf it's it's a very good deal also.
Dave's bread it is just under $4.50 a loaf which is the best price around.
Eggs are still under $2 a dozen when you buy a five dozen flat, they stay fresh in the fridge for a very long time.
