Apple Juice is $3.39 for 64 oz.. Coke is $3.69 for 2L--about 68oz; essentially the same price.
I think what's happening here is that the natural health halo of fruit juice is absolutely short circuiting your mind.
Ask yourself: if you added the same nutrients that are in juice to coca cola, would coca cola now be "healthy"?
Wait...so we... w-w-w-won?
