Had a really weird case where imperial slave were at high demand (around 15k demand which is way more then I've seen for slaves, usually around 400 supply or demand), but were sold for 5000 when galactic average is over 10k. I think ATM it is also bugged. The distances are insane sometimes also, farthest I went was 50kls but I did find very cheap tobacco there so wasn't a total waste...
