Quality (White Giant)

Hello,

I've a question about quality of products. If I buy a product for a price of 1000SC (While the market price is 1400) and I get the requested amount of units in quality 270, I have bought it for the price of 2700SC a unit. If I want to sell it, I can only sell it for the max of 2000SC a unit. Isn't there a possibility to change the quality to quantity or something? Or how can I prevent of buying this high quality of products...

when you sell it, the price you set is for 100Q, so selling 270Q for 2000SC would actually sell for 5400 SC

Ok, thanks for the fast support!
