Which product should I choose?
The Quick Answer: API
When should I choose the Factory product?
Currently, only our Factory product supports the building of comparison sets. If you absolutely need this functionality, then you should choose our Factory product. You can learn more about building comparison sets with our Factory product here.
Additionally, only our Factory supports the ability to add Amazon products. However, through the use of other 3rd party plugins such as the WooCommerce Amazon Affiliate plugin, Amazon products can be added to your WooCommerce store if you are using the API product.
