I would like to ask for the help of Magento community to solve a problem. I need to know how to decrease stock not after an order is placed but after the product is added to cart. How can I do this programming? Does anybody have an idea? Yes, I know this is not recommended but I’m working on a development of an online store and the customer (store owner) requested this to my boss and I have to do, simply. Please, anybody could help me with this damn idea?
