I'm trying to understand the math here, and think they just arbitrarily made up a $$ value out of their ass
Under $3 is free. OK thats easy
hit $3, charge $10. so they assume 3.33 gallons used to break even
Hit $4, charge $30. now I can buy 7.5 gallons of fuel for the delivery surcharge
hit $6, charge $77.50. Now they can buy ~13 gallons of fuel for the delivery surcharge
seems like a shit system that I'd argue if I bought from them regularly. linearity doesn't make sense
I understand a flat delivery rate to cover wear and tear. and starting with a flat $$ amount for delivery makes sense, short deliveries you make a little and far deliveries you lose a little to average it out. This arbitrary growing cost/gallon doesn't make sense to me
