seven-cents-a-bag tax goes into effect today. Plastic bags were legalized just so they could be taxed. It's what Rahm Emanuel calls Chicago Values.
So if I make the mistake of driving five miles south of my home to Chicago--which already has a higher sales tax rate than Morton Grove--to shop for groceries I'll have to pay a bag tax if accept bags--whether plastic or paper--to lug my purchases into my car.
However, if I buy groceries with food stamps, then I don't have to pay the bag tax.
