Let me fix that subtext for you...

So now Walmart is charging for bags. Because you know, it's not enough that they have TAKEN OVER THE EARTH (at least, all the parts where commerce and trade happen); now they want to save it too! Rah, rah, sis boom bah. 

Fixed: "Together we can reduce continue to use plastic bags waste to keep but YOU'LL have to pay for them; we really couldn't care less about our planet healthier!"
