Editing listing settings allows you to set parameters around individual listings that will override your global settings for that item only.
With this feature you can quickly and easily change your product ID, should the ASIN or ID change on your vendor's website, to override global settings for the quantity and margin percent of a single item, or to disable PriceYak functions on that item entirely.
You can also view other item details, including the history of revisions made to that item.
To make these changes, navigate to your All Listings page and find the listing you want to edit. You'll find the Settings button in the right-hand column of the listing.
Be sure to save any changes you make on this page by clicking Save near the bottom of the screen.
