I despise the things and have used my own  bags years before it was 'the thing' to do - BUT why can't stores just charge for plastic?  I bet you would have a huge decrease in plastic bag use if shoppers had to pay ten cents per bag.  I hate to see more regulation or taxes. Simply a write in campaign to the most offending merchants will get results ----- that is how we got black plastic covers on the front of Cosmo magazine at the check out counter.  It works 😉.
