ngl, you sound like someone who has never been a serious gene scroll seller as a scroll with even a minimum discount will sell far faster than a scroll higher than MP, so within a couple of sales your 'strategy' fails and might (might!) only work for someone selling a couple of items. Therefore I doubt that any active scroll seller, especially as prolific as Ellipoo, is 'gambling' on dozens of scrolls they are selling.
