Is it advisable to mix brands of gasoline?

I always purchase Exxon gasoline because I know that it is quality gas and also because I have a credit card for that brand. Recently two Exxon stations where I've purchased gas over the years have switched brands to Shell. I don't have a credit card for Shell, but I could apply for one. The Shell stations had cheaper priced gas than Exxon Stations that I pass. Therefore, I was wondering if mixing gas of two different brands cause any problems for the car or should I have no problem by using both Exxon and Shell gasolines?
