I am having trouble finding a UPC code from my supplier. Is it ok to just use a new UPC for the product or do I have to contact my supplier for every item I want to list? This seems very time consuming. I haven't found the products on Amazon either so I can't just piggyback off of an already listed post.
If you don't have the UPC Codes, you will have to get new ones, I have been using Link hidden: Login to view for a very long time for Amazon, Rakuten and Sears and I haven't had any problems and fast service.
