It would be nice if the customer would receive a message when an item is on sale that there is a maximum of 50 in stock, for example. The current situation is that a customer with a stock of 50, for example, can first add 25 and then 28 to the shopping cart and is only shown in the shopping cart that only 50 are available. It would be more customer-friendly if the customer received a message as soon as the stock is exceeded.
