There are some situations when you do not want users to buy multiple quantities of a product in WooCommerce shopping cart. Typically, you would like to restrict a user to buy only a single quantity of a product. It might sound strange, as what’s the difference if a user buys one quantity or all of them. However, it’s a bit more complicated than that.
Here are some of the situations when you would require one user to buy only one quantity of a product:
1) Digital product: If you are selling a reusable digital product like an eBook or a software license which can be used in multiple instances. For Example, if there’s a digital product like Genesis Theme Framework, which can be used in many sites. A user has to buy a single theme framework which he can use in multiple sites. It doesn’t makes any sense for a user to buy multiple licenses for this product.
2) Limited stock: Say, you have limited stock for a particular product and you want that every user should at-least get a chance to buy it. Instead of one user buying all of them at once. Restricting a single user to buy multiple products in such a case will make many users happy than one user.
3) Tickets: If you are selling limited number of tickets in your WooCommerce shopping site for an important event and you wish that the tickets should be spread among different people.
