If you want to list a product that is already on Amazon, but it has incorrect information, what should you do?

When a product already exists on Amazon with incorrect information, the correct procedure is to work on updating the existing listing. Amazon's policy generally prohibits duplicate product listings for the same item. If you create a new listing, it will likely be suppressed or merged, as Amazon strives to maintain a single, authoritative product detail page for each unique item. By attempting to update the existing listing, you contribute to the accuracy and quality of the Amazon catalog. Not listing the product or deleting the listing are not viable options if you intend to sell the item.
