Anyway. Stumbled upon their sparkling water - which comes in tasty flavors - black cherry, cranberry-raspberry, white grape, and more! - at my local Jewel recently and I'm hooked.
I don't always like the SuperValu/Albertson's store brand products, but this one is awesome!
0 calories, sweetener is sucralose, and about $0.79 - $0.99 for a 1 liter bottle. (also available in smaller bottles, 4 packs) In the aisle with water.
(This isn't the sparkling water, of course, but you see the logo)
