Hallo, I am running on a fresh install of Zen Cart 1.3.8a building a store with products that are not available in quantities. Usually, there might be one or two.
If a customer adds one product in its basket, the quantity is not substracted from the product's page. This means that if another client simultaneously puts a product in its cart, at the end one of them will be disappointed.
Is there a way I could guarantee that everything existing in the basket will be available at the checkout?
