I gotcha. Over the life of using the app, it's saved me damn near 500, and that's odd I tracked it through the app which I didn't always do.
I take premium though, so when prices shot up above $6.30/gal, it was nice to see who hadn't jumped yet and save a little. Being that it went from ~$4 to $6.20-6.30, an extra $40/week in gas was killing me. That's over $150/mo and, honestly, money is tight with everything else bring high, so. Just feels good to not feel like it's money wasted. I know it's not much, but it males up for times I'm not so stingy with money.
