I keep saying I need to use reusable bottles for refilling with water. My husband does it, using RO water. I admit that I'm lazy and I buy bottled water by the case at Sam's Club. One case goes in the refrigerator in the garage, a few bottles in the freezer, and the other case goes in the pantry until space becomes available in the frig.
Hubby bought me a case of different sizes of BPA free plastic storage containers and I still haven't put the old ones in the recycle bin.
