Re-Order Products
From the Store Administration page, scroll down to the Simple Catalog section and click on Products.
Select the product that you would like to re-order from your list of products.
To change the order of the product you have selected, click in the Weight field and enter the number/position you would like the product to appear in on your site. The lower the number you enter, the sooner it will appear in your list. Enter 0 to move the product to the top of the list, followed by products numbered 1,2,3, etc.
When you are satisfied with your new order, click the Save button at the bottom of the page. The new order of your products will take effect immediately.
