In addition to the money you save with the CMax, you can also get rebates at the pump every time you fill up your car or anybody else's car. Just run this app before you fill up. Claim the gas station and then send in a picture of your receipt. The next day or so they rebate money back to you. You can cash out and get a check in the mail or they can send you money via PayPal. https://upside.app.link/tZsp0zL0HO Only use this on a smart phone. This only works for credit and debit. So don't use cash. You can get like $.20 to $.30 cents off per gallon. You don't have to buy or sell anything. It's like free rebates that you're be giving up all this time and will now be able to get them. As far as I know, this may not work in Georgia, but it works in most parts of the country. If it doesn't work in your state, post it here so people don't waste time installing it. It seems to work in major metro areas. I use it and all my friends are getting money back every time they fill up. It was on 103.5 WSHE down here on the radio.
