Valero in Corpus Christi (4202 S Staples St)

This is the station that has the cheaper gas prices close to where I live but only because they stay competitive with Walmart down the street. What I don't like is that many times their gas cards can't be activated because the machine is not working. When that happens, I don't waste time going to another Stripes just to save a few cents, I go gas up at Walmart which I'm pretty sure a lot of people do as well.
