I am sorry. In BO, you can set an option “Available for order” for every product. http://snag.gy/1EDUf.jpg

When you uncheck this box, you want to keep the product on the site, but without an option to order it. In the default theme, it works http://snag.gy/ZNlF4.jpg. But in AVAZ theme, there is Add to cart button on product page, even if it is not available for order.

I would like to remove this button, or better solution, replace it with button of similiar size, but it would be red and says “Out of stock.”
