Mott's Selling 50% Juice For the Same Price as 100% Juice
Mott's Plus Light Apple Juice has "50% less calories and sugar than 100% apple juice"—because it's watered-down. Consumerist compares regular Mott's apple juice to the light version, and while the light has higher levels of vitamin C, vitamin D, and calcium than the regular, the light juice is almost the same for twice the price. Perhaps it's convenient if you can't add water to 100% juice by yourself.
