CVS is running a special this week on their Nestle water. I had a devil of a time trying to find a CVS store in my area that had the water. Many of the stores told me they substituted the water for another brand because the delivery truck didn't bring the water.
The water is on sale for $2.88 (reg$ 4.99)
I used a Nestle coupon for $1 off 2 packages of water, which brought my cost down to $2.38 for each one. This brings the cost down to under .10/bottle.
