That's a double edged sword.
On one hand, yes I get a discount on rebuy.
On the other hand, it's so small I may as well not have it. It makes no difference whatever.
Except for one thing, I can't give you any accurate info on how much anything in the game costs to buy.
For example, you ask me how much is an Imperial Clipper, and I could say it's Cr 19,000,000 but then you go and it's Cr 21,000,000. Now, you don't trust anything I say because I already gave you wrong information.
Honestly, I'd rather not have a discount at all, especially as credits now are so easy to get, the tiny discount means nothing.
