Infinitus, players who sell the dust are usually the ones who don't feel like keeping the dust for later on and need the money from synthesis right then and there. For whatever reason, they put it up there. It's cheaper to buy it from Stinknix, and it garners more profit for poison potions.
Just because you can now buy Yellow Globes for 2K instead 3K, doesn't mean you have to undercut these too! Increase your profits when costs decrease...
