I am trying to set minimum order quantity for my product under $30 in order to keep my profit for selling per unit goods. The thing is that I am not able to set it from anywhere. There is no any options to set minimum order quantity that results loss in sales.

I know amazon is customer centric platform that focus on the convenient of buyers, I appreciate it. But I want to request that if amazon allows the options to set minimum order quantity then customer also get the desired quantity and seller also remains in profit and loves what amazon is offering to both parties.

Or if it's already on amazon and i didn't found that. Anyone having experience can share the knowledge to do it.
