Scrolling down below the eCom Mobile Home Banners, you will find the Mobile Featured Products module (also known as the Featured Flex module). The products displayed by this module can be filtered by category or by brand, and can be set to display any number of products, though 3 is recommended. The products will be displayed by the date modified, with the most recently edited item first. Be sure to specify where you would like to pull products from when setting up your mobile site.
This module is included in the cost of the eCommerce Mobile package, or for clients who already have eCom mobile, it can be added in for a $25 installation fee.
