I think honestly I could save as much money staying home the entire time,
save myself the $7.95 on the edging, the cost of driving to-from the store,
plus the hassle, I figure we can round this up to an even $20.
Personally I didn't see much improvement if any.
Assuming this POS improves a car's fuel mileage by 10%...
But that's assuming a lot, what if it's only 1-2% improvement?
However at 3 dollars a gallon we have ourselves a 30 cent per gallon gain,
and it would take 70 gallons of fuel to pay for that $20.
And start praying to the backwind gods.

A guy on a Cummins forum said he got better fuel economy from an aerodynamic improvement? Those guys usually say that they get the same MPG towing a camper or large boat as they do unhitched.
