Téma: Gingerbread

I would like some admin to answer this question: in the Gingerb exchange table, for 180 GB it is written "30 credits, 30% bonus on credit purchase".
Does that mean we get 30 credits AND also 30% discount for future credit purchase, or does it mean we have to buy credits to get any advantage from having 180 GB?
Just would like to be clear.

That mean get 30 credits AND ALSO 30% discount for credit purchase
