I found these Canadian sodas (also available on Cranberry & Raspberry, Cranberry & Blueberry and Cherry flavors) at the 99-cents store and I was intrigured enough to try them. They are organic, and GMO free, and have no artificial colors or flavors. They also come with the recommended daily value of vitamin C. And at 3 for 99cents, they're pretty cheap.
Alas, I didn't really like it. It's too sweet for my taste, it tastes mostly of lemon oil with a hint of coconut (must be the "oil" aspect of it). I couldn't even finish the bottle.
