only one problem guys.... I just tried to enter the word EXEMPT into the barcode section of Ninja Lister..... it will not allow anything other than numbers to be entered!!!!!UPDATE - Google Shopping exemption system changed. If your product has never had a barcode associated with it then you can use the word EXEMPT in the barcode box on listing form. If it has then you'll need to add it to the barcode box to enable your item to be uploaded to Google Shopping.
