Nicodemus,

I didn't say I have a lot of them (yet), just that as I empty them I recycle them to store water. If I did the same with every 2 liter soda bottle that came into the house I'd probably have enough water stored to fill a swimming pool.

Since you asked, my wife is a Registered Nurse. She may use more than the average amount of bleach in doing laundry. That said, we might go through a 3-4 bottles of bleach each year. It will take time to accumulate as many as I'd like, but once I have them I think they'll last a long time.
