No. It's like paying $30
If you're going to be filling up a complete 20 gallons then you would be saving an additional $10 by buying a fillup at $35.Vs at $15 for $1.55 off.
We can do the math together.
Gas at the pump is $3.17 a gallon.
With the $1.55 off the gallon ($3.17-$1.55 we would get $1.62 per gallon.
Then × that by 20(as 20 is the max you can pump with one code.) $32.40 +$15=$47.40
Vs
$35 for 3.05 per gallon.
3.17-3.05= $0.12
$0.12 × 20= $2.40
$2.40+35= $37.40
Hope my numbers are somewhat correct at this time of night.
