You can get free 1lt bottles of Sparkling Water at Target this week and next. Go here to get a $1/1 1lt bottle of Sparkling Bottle printable coupon. Make sure you enter your local zipcode to get the right coupon for you. This company markets their Sparkling water under different names in different regions. In my area the brand is Poland Springs, but other areas may know it as Arrowhead, Zephyrhills or Ice Mountain.
Target sells the 1 lt bottles for 99¢ regularly and it looks like next week they will be on sale for just 69¢.
Thanks Thrifty Couple!
