Inasmuch as these are all pretty much the same from a quality standpoint (regardless of whether they are purified or come from magical springs somewhere) I applaud a decision to cut costs in an area such as this. The whole bottled water fad is just another way to generate more waste in any event.

There are certainly differentiated products where it is beneficial to spend money (and AA usually doesn't there eithr) but bottled water is certainly not one of them.

Cheers.
