Answer : magento how do I display all the products in a single page?

- This is not the latest version: current is 1.3.1

- To easily display all the "promotion" products, it would be best to indicate that these products are in the promotion category, and to display this category. Then your visitor will be offered the choice to display 9 products, 15, all of them...
