Please never sale your products with Amazon Seller Central.
My experience has been frustrating with there difficult website to navigate. With lots of complicated rules. And there's so many things on their sellers website it's overwhelming. If you have questions about a product you're selling. They will most likely want you to email them. There is a way around it. When you have the Option to pick advertiser or seller. Pick advertiser and they'll suggest you give a email or phone number. Click the button that says immediate attention Call Me Now. Is how to reach customer service over the phone. Because they don't have a direct phone number line to call for help. I've spent way too many hours trying to figure out their website.
