This is a scare tactic that big businesses have put in their ads to get people to vote no.  Do not be fooled!  The only way to do this is to tax gross sales as there are so many tax loopholes allowed if net is taxed.  Most products that will go up in price are not necessities, which means you don't have to purchase them.  Less consumption is good and taxing the wealthy businesses is good.   This is a much better alternative to clear cutting our forests for the schools and other needs.  Look at who has given money to fight this....logging, out of state corporations, etc.  Follow the money and find the truth!
