i have noticed that even if the product is "Out Of Stock Status" still visitors can go through the Checkout process
may be some extensions out there to display some kind of warning or terminate the Checkout process because logically the product is out of stock.
however, in my admin/settings/option:
- Stock Checkout:
Allow customers to still checkout if the products they are ordering are not in stock.
set to NO
- Show Out Of Stock Warning:
Display out of stock message on the shopping cart page if a product is out of stock but stock checkout is yes. (Warning always shows if stock checkout is no)
set to Yes
but still can not see
