I just realized that Costco in Lake Stevens, WA vs Marysville, WA was 44 cents difference. about 10 miles apart. I think it is because of higher incomes near Lake Stevens. They have a lot of Boeing people/higher income. Also the Lake Stevens location is only about a year or so old.
What accounts for the difference?
Edit: Lake Stevens Costco $4.13 gall
Marysville $3.69 gall
