I'm trying to find some water flavoring powder/liquid whatever that uses sucralose or stevia. So far the only sugar free stuff I've found have been in super expensive little squirt bottles or individual serving packets. I want something that is good and comes in bulk so I can make gallons of the stuff at a time. Anyone know of anything?

Crystal light came in pitcher size tubs....not sure if that is what you are looking for but where I shop they are usually near the top of the shelf.
