if the product is the same, i would suggest maybe some kind of bulk discount, nav standard 75l tank and last the average user a week or 2, cant cant usually fit the highflow nozzle in vs truck usual minimum 2x 700l tanks and lasts the average user about 2 or 3 days, and would take for ever to fill from near empty with a normal nozzle, and if you are paying for a fleet, i think you could see how that 2c adds up pretty quick.
