Coca-Cola has been focusing on selling more 7.5-ounce (222 ml) cans in displays near supermarket checkout lines.
Previously, Coke had relied more heavily on 20-ounce (592 ml) bottles displayed in the beverage sections of supermarkets. An article in the Wall Street Journal noted that, The smaller 7.5 ounce mini-cans are typically priced at five to seven cents an ounce, compared with three or four cents an ounce for 12-ounce cans. It quoted a Coca-Cola executive as arguing that consumers don’t care about the price. They will pick it up if you put Coke within arm’s reach.
