"Coca Cola" has been judged and not recommended by a lot of people. Obesity is one of the major issues that Coke faces. Doctors tell their patients how coke can affect the human body and that doesn't look very pleasing at all for the consumers of the product. That is why "Coca Cola"introduced new products that are supposed to be healthier, like the Diet Coke, Coke Zero.
Sales promotion is good to companies to attract new customers by lowering the price of a product and offering them more. Better products and more reliable ones will catch the customers attention. "Coca Cola" also has a promotion with Six Flags. If you bring a can of coke with you to the park, you get a discount on your admission ticket.
