The Corporations have been passing through any taxes they have to pay for their customers to pay instead for  decades.  

Kick up Albertson's or Safeway's or Winco's, or Wal-Mart's taxes and see the price of your loaf of bread go up.  

Just hope they only increase it enough to cover the new taxes and don't program their computer to add an extra percentage or so to increase their own profits and then blame it on the new taxes!

Since they will all be kicking it up at the same time, there will be no competitive disadvantage between any or all of them.
