To specify the sort order of your products within a category:
Log into the Content Management System
Select 'My Online Entries' from the left hand navigation
Filter entries to show products only
Click on a product 'Entry title'
Scroll to the bottom of the page and click the button 'Specify Sort Order' to the right of the field label 'Category ranking'
Use the shuffle tool to order the products in the category
Save and exit the entry
Note: you only need to set the sort order in one product entry per category; it will automatically filter through all entries in that category.
Repeat the process for all categories where you have more than one featured product.
