Elon Musk said they will be able to reuse the two halves of the fairings. The fairings are the nosecone of the rocket. The nosecone splits in two to expose the rocket payload after the rocket has cleared the atmosphere.

The two halves are fairly light but they cost about $6 million. SpaceX charges about $62 million per launch but they are making more than a 30% operating profit. SpaceX has waterproofed the fairings and has parachutes on them so that they are not damaged when they land in the ocean.

The profit margin on any future launch using reused fairings will increase the profit on that mission by 10%.
