Yeah, I regret adding the “free” part because I didn’t intend my comment to be about cost. But in terms of convenience, is it really so much more inconvenient to bring a reusable water bottle with you to the store? Why add to a landfill by getting a disposable cup every time you go?

Since we’re on the topic of cost though, do you know how much 16oz of water from your tap at home costs on average? 3 one hundredths of a cent. Thats about a penny and a half a year if you go to the grocery store once a week.
