B2B sales is a different game that can be a two-way conversation rather than just supply and demand curves intersecting at a price. Often there is competitive analysis involved before choosing among alternatives and a vendor will want to make sure their product is best represented in that view. It’s also a chance for them to learn any other decision factors (besides price) they might be able to address. In this case, I suggest the novelty of pricing out a rocket launch is partly clever promotion, though also aspirationally a first step towards regularly booked space services.
