In the late 90's I used to work for a goverment agency which bought fuel in bulk. At the time we were paying in the mid fifty cent range per gallon, exluding state and federal taxes, which totalled somewhere around 35-38 cents, for a total of .95-$1.00. Retail was probably $1.10-1.20, if my memory is correct. I remember the margin was pretty low, maybe 10-20 cents, so these figures seem to tie.
