It is not a secret that making similar changes to multiple products may be a monotonous and time-consuming process. It helps a lot when you can edit multiple products at the same time. In X-Cart, you can do this using the add-on Bulk Editing.
With the add-on Bulk Editing installed and enabled in your store, you get a new tool on the product listing page of your store Admin area - Bulk edit all:
With this tool, you can enable/disable products, put products on sale (or end a sale), and change other product properties (categories, tags, inventory, prices, etc.).
