A beautifully simple concept - a store whose focus is entirely one thing: water. They have bottles in different sizes for you to purchase - from individual water bottles to 5-gallon bottles. Whatever the size of your bottle, they will clean it (using a rather nifty sanitizing station) then fill it with pure water for you. It's just a quarter a gallon, and they keep track of your purchases on an index card so that every hundredth visit is free. I didn't realize they did this until my last visit - which turned out to be the hundredth one! They will usually help you carry your filled water bottles out to your car, too.
