I shop vons/pavillions which is owned by safeway, and they carry the vitamin waters. Zero Revive appears to be a big seller...I'm thinking due to high potassium content....other smart people out there too. I hope. Often the zero water is .99 cents, 5 for 5.00, it was no on sale so I paid 1.59 for a bottle, bought 2. I drink a 1/2 bottle at a time...
