These bans are based on a big lie. That the bags were single use. I always used mine 4-6 times. In CAL you can now buy thicker bags for 10 cents. So you pay the state money and get a bag which is less biodegradable. Its just a boondoggle to increase tax revenue.
The state does not get the money. The retailer collects and keeps the 10 cents to pay for the bags. It is not a tax.
