Hi Erin,
You can change the number of "Product Catalog Columns" in your Cart Settings to 2 or 3 columns which will show all of your products without having to go to the next page.
Or If you would like to keep the single column layout but increase the number of products on the page, please see the following forum post for instructions on how to change the number of items displayed on the ProductList Page: https://www.smith-consulting.com/Foru...
Thanks, Kevin
