Noticed a satellite uplink (small one) on the roof of my local.  Sales
figures are uploaded daily to the fuel provider so adjustments in price to
the local seller can be made based on sales.  My seller makes about 12-15
cents a gallon and is contract-bound to a particular distributor who sets
the price at the truck.

Odd, that.  Not fair sez I.   Especially with camping season upon us.
