Not only that - it's kind of a flawed comparison anyway.
None of the F9 boosters are orbital vehicles, i.e. they cannot even be compared to the Space Shuttle since their only commonality is that both are rocket-powered vehicles that crossed the Karman-line.
There's simply no good point of comparison at the moment since the F9 is the first of its kind.
I was curious about the space shuttle solid rocket booster, so I looked it up...
Out of 270 SRBs launched over the Shuttle program, all but four were recovered – those from STS-4 (due to a parachute malfunction) and STS-51-L (Challenger disaster). Over 5,000 parts were refurbished for reuse after each flight. The final set of SRBs that launched STS-135 included parts that flew on 59 previous missions, including STS-1. Recovery also allowed post-flight examination of the boosters, identification of anomalies, and incremental design improvements.
It is a flawed comparison in the other way as well. The shuttles required vast amounts of refurbishment after each flight. While the thermal protection system was improved with the later shuttles, they required a lot of inspection and replacement of individual tiles, which was an enormous cost. It was also standard for the main engines (SSMEs) to be pulled out and swapped with ones that have been fully inspected. Even the solid rocket boosters (SRBs) needed to be towed back to port, disassembled, and completely refurbished for each flight.
The F9 first stage, on the other hand, typically goes through a relatively light amount of inspection and repair after each flight.
Per-flight costs for the shuttle was $1.6 billion USD (2010 dollars). A good chunk of that was refurbishment for the shuttle and the SRBs. I didn't find specific numbers in a quick Internet search.

That was the improved cost. In the late 80s I interviewed at the contractor running shuttle ops (Lockheed missiles & space?). The head of the NASA project office told me it was close to 2.4 giga$ to turn around a shuttle and they hoped to cure that with a new prime contractor arrangement (and also fix the management problem that was the proximate cause of the Challenger disaster, but apparently only suppressed it for a time...)
Isn't that the cost of the entire space shuttle program (including R&D) divided by the number of launches? I believe the real cost of turning around a shuttle flight towards the end to the program was a fraction of this.
I wonder what the cost of a currrent spacex flight is doing this same kind of accounting. I don't suppose anyone really knows since spacex is a private company.
In some sense, the Shuttle program was in continuous development. But to give you some idea of the work involved in even the later launches, consider this:
Instead of inspecting 24,000 tiles by hand, they developed a scanner to automate the process starting with STS-118:
They had hundreds of techs, working thousands of hours per launch to get each orbiter ready. SpaceX is expending a tiny, tiny fraction of that effort to get each stage-1 booster ready for re-flight. Part of that of course is that the booster is coming back at sub-orbital speeds.
So it is more fair to compare the F9 stage-1 to the pair of SRBs used for the Shuttle. But even then, there was a lot of effort just to get the SRBs ready for re-flight.
Just because all their current flights so far have burdened them with enough payload to not achieve orbit doesn't mean they aren't perfectly capable of orbital insertion and manuevering. Don't forget they do have to do a deceleration burn once they release their upper stage; because without it they would continue on a trajectory that could easily carry it 2/3s around the world before hitting atmosphere again.
That being said you are kinda right in that they really can't be compared, considering the shuttle is more a payload with a really awkward engine arrangement and can't actually reach orbit without ditching multiple SRMs and a fuel tank larger than it is, but can actually do useful stuff once up there.
Yeah but think about the difference in cost the space shuttle alone costed almost 200 billion dollars over its 40 flights its still 5 billion dollars a flight. Now compare this to these boosted they don't include a mission module but they cost about 62 million in there first launch and following launches are only about 15 million dollars. Note to mention the pace of launches are much much faster than the space shuttle. These may not be orbital boosters but they don't have to be these costs demonstrate the mistake with space shuttle is trying to do to much. Now I cited the total cost of the space shuttle and but to say just because these boosters haven't reached 39 flights so they are a long way off is silly they did this in 2 years the space shuttles lifetime was like 40 yrs.
I don't think that comparing this booster with the STS is particularly valid. While I don't want to downplay SpaceX's very real achievement here, the STS was a much more complex and flexible platform, it was human-rated (with all the engineering overhead that that entails), it was built without the advantage of the last forty-plus years of technical development, and it was done first. All those things cost money - at the time or with hindsight.
So now it trails two orbiters less than while on the drawing board, hooray! (if we include Buran, which did make it to orbit but has even less in common with Falcon 9 because the engines of the reusable part are upper stage)
