Overview
If you notice that the “Add to Cart” button is missing on certain products, check whether those items are priced at $0. By default, zero-priced products on B2C sites will not display the Add to Cart button.
If you would like customers to be able to add zero-priced items to their cart (for example, free samples or promotional items), you can enable a site feature to allow this.
Steps to Enable
- Log in to your Admin Panel.
- Go to: System > Site Features > select B2C
- Under Display Features section
- Locate the option: Allow Add To Cart for Zero Priced Items
- Switch this option to ON.
- Save your changes.
Direct link to the settings page: /admin/msite/features/public
When this option is enabled, products with a $0 price will show the Add to Cart button.
Conclusion
-
If the option remains OFF, the “Add to Cart” button will be hidden for zero-priced items.
-
Decide carefully if this fits your business rules, some stores prefer to hide $0 items, while others use them for free or sample products.
