OK, I accidentally dropped the decimal point. You save $.10 per gallon up to 25 gallons for every $100 you buy in the store. The limit is 500 points redeemed for $.50 off each gallon up to 25 gallons. ($12.50)
Since my tank is so small, I usually have to refill when I only have 200 points. and, only get $.20 per gallon savings on 10 gallons. ($2.00)
An additional 15 gallon tank would allow me to drive longer and build up my points to the maximum savings of $.50 per gallon.
