Probably by an order of magnitude if you factor in all the externalities. Unfortunately, those externalities probably won't make a difference on the sticker price.
Obviously that's not the point.
It's a pretty big point, if you want your product to get picked up by margin-focused corporations.
Some countries are making manufacturers/shippers legally responsible for their waste, they can no longer pass on their externalities to others. Doing that can help shift the decisions on packaging.
