At Qspray.com, we are occasionally asked, "Where's the Add to Cart Button"?
The answer is simple. If there is no ADD TO CART button, it means the item is out of stock.
Why do we do it that way?
Easy. If we put an add to cart button when the item was out of stock, our customers would order the item.
We would then need to call them and tell them the item was out of stock, which would cause upset.
We know this from personal experience.
Anyway, that's why sometimes there is no ADD TO CART button.
