$COST (Msges, Tweets) cut $KO (Msges, Tweets) bc Coke wanted to charge more. If consumers don't want to pay more fore sodas, what will they want to pay more for? Not much.
Interesting to me that COST (Msges, Tweets) not carrying KO (Msges, Tweets) products is such big news. They only carry 4000 items w/price advantages. KO (Msges, Tweets) needs to play.
