Updating Delivery Charges and Zipcodes
Use your admin login information (back panel). In the bottom right-hand corner you will find the Delivery Settings icon. This will bring up your current list of delivery settings.
Here you can click on the edit button for the zip-code you want to update. Or, click on the last blank option with the (+) symbol to add a new zip-code.
A new window will appear to make your changes.
Make all your necessary changes and then click the “Submit” tab. Your changes to those areas will now be saved in your delivery settings.
