Par4QC Our Krogers don't have Shell stations, but our Shell stations have a 0.10 a gallon discount with Kroger card (assuming you've spent over $100 at Kroger since last fill up). Ain't much but it saves a couple of bucks. I always use Shell anyway just because they issued me a credit card when other gas companies wouldn't for some reason. Have only bought other gas when driving through regions that don't have Shell stations.
