Hi,

I come across multiple question, just wanted to give a update that I have used this free version App by https://ahex.co for Ecommerce Minimum Order Quantity and it worked perfectly for me. Who ever are looking for minimum order quantity, should give a try to it once. I can set different minimum orders for each of product separately.
