DOSH is an app that lets you register a credit card and then gives you cash back when you use that card at a participating merchants. They added Exxon Mobil to their list of merchants a few months back at a rate of 2% cashback. Now they have increased that rate to 3%. You should see the offer in your app.
A decent offer that could net you some extra savings on your gas fill-up without much effort. What makes this even better is that it stack with whatever credit card points that you earn. You could earn 10X with an Amex business card for example and also get the 3% cashback from Dosh. You just need to use a linked credit card and you’ll get 3% cashback.
If you’ve never used the Dosh app you can also get a $5 signup bonus and an other $2 for linking card
