"Hi UltraDiesel. When you report the Diesel price at the Shell/Flying J (Highbury/401 in the south of London) please report the credit price (the higher price) not the cash price. You could add a comment that says "1c cash discount for Diesel" if you like. See question 16 at the FAQ here: http://www.londongasprices.com/faq.aspx#16"
