When you update your Seller Info tabs within the Settings section of the Frooition software the changes are not automatically reflected on your live listings.
This is because the information is held within the HTML code that makes up your template design.
In order to get the changes onto your live listings you will need to either:
Use the Bulk Revision facility within the Frooition Software, selecting the Update Seller Info option
Use the "Get Code" button (at stage 3 of the template profile) to copy the HTML code from your updated template and then revise the items in eBay, overwriting all HTML code within the eBay description with the code you have just copied.
