Option to accumulate rewards for $.10 off / gallon after 50 gallons purchase, does not translate to $.10 off on next purchases totaling 50 gallons. I was led to believe that would be the case, when in fact you have to purchase 50 gallons all at once to get $.10 off/gallon. This deal is only useful if you have a truck size tank to fill, not mentioned in the details of rewards. So this deal is worse than $.06 off / gallon using a debit card. This latter deal is not as good as Cumberland Farms deal of $.10 off / gallon using a debit card. User's recommendation: Go to Cumberland Farms.
