The cost of ocean shipping is a tiny fraction of the consumer price to Puerto Rico. A can of soup that retails in Puerto Rico for $1.81 costs just $.04 to ship. If consumer goods are sometimes more expensive in Puerto Rico, it is not because of the Jones Act. Consumers buy goods from retailers and grocers, not from shipping companies. Retailers buy the goods from shippers and determine the price of the goods to make a profit. This price mark up reflects labor and real estate costs as well as supply, demand and profit margin for retailers. These costs are not affected by the Jones Act.
