Are you saying you pay 40k per charge? Or is this 40k for 100? Normally when I have it, I charge 75k per 100, and cannot keep it on there, it takes more time to get the zoogi then it does for the powder to stay on my vendor. When I do get it, I see major players from Luna buying it up real fast.
Been slow with the zoogi since the Tokuno event, and also going to Magincia for more threads for the up coming Cloak's quests. But I will try to make a run today.
