Listing section "from the manufacturer"?

Hi,
You’d need to be a Vendor and have a Vendor Selling account to be able to do that.

Can I publish my content to "From The Manufacturer" on the detail page?

No, this section is reserved for A+ content from retail vendors.

(A+ content from sellers shows in the Product Description section of the detail page.)
