Interestingly.....the cost to travel from Yavin to Nar Shadda is 300cr. If you choose to exit to Nar Shadda, the cost is also 300cr i.e. those prices match. Similarly, the Yavin-DK cost is 100cr, and the exit cost also 100cr.....so again, a match.
But can we talk about why it costs 100cr to travel through hyperspace in a personal ship but 20x that to hail a taxi dirtside?
