Water, Water Everywhere

I know, I know. We should be re-using a water bottle every day for the sake of our earth. And sometimes we still do. But sometimes it's awfully convenient just to grab a bottle of water out of the fridge. It's definitely more convenient for my son, who takes one to school every day. And refills it all day long from the water fountain. He's even been trained to return the bottle home so we can return for the 5 cent deposit. A case of "name brand" water goes anywhere from $3.49 and up. Aldi water? $2.79.
