Hilton Honors Points for Coca-Cola Purchases
I apologize in advance for not knowing how to link to other areas of Flyertalk, but there is a discussion about a new marketing program in the Delta forum involving Coke products.
Apparently, you earn "Coke points" for purchasing specially-marked Coke products, and then you can redeem for a variety of prizes, including Delta miles and HH points.
Accoring to the discussion, the points are only being offered currently for 20 oz.-sized product.
