Of course it is. So let me ask you this. In 2009 Exxon Mobile didn't pay any income tax. Did they use that savings to slash their prices thus undercutting their competition and gaining market share? I don't believe they did; their prices were the same as their competitors. So I guess they didn't study their history, huh?
You just made my point for me. They paced their pricing to track with that of their competitors.
Still, using oil companies is not a good example to use, because of the dependency on foreign supply lines and other forces that shape pricing. Plus, in 2009 Exxon Mobile was trying to figure out what the next shoe to drop from the Obama administration was as they waged war against conventional energy producers. Also, being one of the larger oil companies, they invest more in exploration and exploitation of new resources than their smaller competitors.
And guess what. I don’t buy my gas there, because there are other, less pricey choices.
