I just love how products think of new ways to improve their system or the products itself.  The perfect example would be the Poland Spring Water.  Do you know that their bottles can actually be stacked up?  Yes! It can be stacked up on top of each other.  It really is a space saver.  The ones that we have at home takes up most of the kitchen stock room space because we normally have around 15 bottles per week and you know  how much space that would take.  Aside from that Poland Spring Water has an eco-shape bottle. They are really doing their contribution to the world by producing "less plastic" bottles which is actually more good to the environment.
