I have little need for reputation so I chose to get a high level of aggressive negotiations. Now it says I pay 90 reputation for each discount.
I assume that unlocking science parts is a single transaction.
But is making a ship with 4 of the same part 4 rounds of aggressive negotiation so 360 reputation.
Or is it calculated per part with an unlimited number, so 90 rep.
Or is it only charged on unlocking parts?
