Yes, just to add to Katie Berger Tremaine's answer to How much can the Falcon9 lower the launch cost? it's also assuming that the reconditioned booster is reliable as the original - if the re-used booster has a significantly higher failure rate it could wipe out any savings, also make companies reluctant to fly on those missions, so they need to be very sure it is as good as the original. Early stages yet in new technology. Planes are re-used many times of course, no problem. One of the problems though with rocket launches is that each test is so very espenxive. Imagine if a plane could only be tested actually in action in commercial cargo flights because each flight is so expensive it has to pay for itself? And on that basis has to be pushed into service after a handful of test flights?

That's the challenge for spacecraft today. Even the most reliable rockets have had only of order a few hundred flights ever.

In future though they'll be able to abort with the cargo safe, so if you have a few flights fail but the cargo is intact and can fly again that will help.
