I used it for a month and got $1.07, and I fill up my tank twice a week.
How? Don't know that I've seen less than $0.05/gallon rebate - that's a buck with 20 gallons? Unless you only used it for one of your fill ups or something?
ETA: Nevermind, just opened mine up & all I see are $0.01/gallon for any stations near me.. that certainly makes it less appealing. Since WFH after covid, I usually only fill up 1-2 times per month. Still might start using it again since it's not really any work to do.
