Does anyone know where to go to get a real fuel card discount with your Uber card? I get .22 at Vons with a $17 purchase and no fee for credit card use. I went to a Shell and they jacked me up .14/gallon for using a credit card, and Uber gave me .34 back on a $22 purchase. I have a couple of credit cards that give me 2% cash back at gas stations, so I might be better off using those, unless someone can provide me with where to go for better numbers. I am thinking Uber is getting 5% back from the stations and giving us pennies, much like Uber pool.
