We recommend that you use the configurable links at the bottom of each store page to provide an "About Us" information page. While originally built to show a seller's terms of service or privacy policies, these can be used for whatever best informs your buyers of your organization that may not be available in your Facebook Fan Page.
Log into ShopTab's admin, click on Settings and then Advanced Options. Change one of the link options at the top of the page as noted below and save it.
The information will show when the buyer clicks on the text link at the bottom of the page as designated below.
