For your concierge items, you can only edit the selling price yourself.
You can find more information about changing the price here.
I noticed a mistake in the product description of my Concierge item. How can I change it?
We also make mistakes and no one knows your item as well as you do. Thank you for helping us to improve the quality of our products. You have the possibility to report mistakes in your own products in the sales overview in the section My products. You can report mistakes regarding brand, category, size, color, condition, material or image quality. Our team will then check your mistake report and get back to you as soon as possible.
More detailed information about reporting mistakes can be found here.
