Milestone: Took 21 months but finally earned enough Speedway points for a free $25 gas card
Slowest return ever probably, but did it all from gas purchases. Just switched to reloading a Speedway GC for the points and discount (minor) with my CC instead of paying at the pump. Still earned the multiplier for gas purchases on the CC and earned extra Speedway points for the same purchase. So it's only cost me a extra minute or so on the trips I needed to reload first. I can live with that kind of return.
I've learned not only big things but also small changes on this thread that all add up!
