Great little packets to add to water, highly reviewed as best tasting. I've heard of backpackers adding the Lime and other flavors to food, which is great. They even have other flavors i was not aware of (orange, grapefruit).
Just throwing up a deal on here if anyone is interested...I picked up a 500ct box for ~ 3 cents a packet
