It's good that every artist can set it according to which discount is acceptable for him. It's new information for me as a seller. :-D
Then I have 1 recommendation that the banner at CGT site should be "BLACK FRIDAY WEEK! GET 3D MODELS WITH UP TO 50% OFF!".
I like that CGtrader is ahead in this way and has already implemented tasks for which artists are calling at other marketplaces without success.
