Why aren't there coke rewards on 24 packs...

I'm wondering why on all the 20 oz. bottles of Nestea they have coke rewards points under the cap as well as on the 12 packs of Nestea cans but on the 24 packs of Nestea cans there is no coke rewards! Why would this be. It annoys me because its a slightly better deal to buy them as large a quantity as I can but then if I do I miss out on the coke rewards. On the 24 packs of Coca-Cola Classic they have the coke rewards so I'm not sure what the difference is why they arent on the nestea 24 pack packages. Any ideas?
