Mascot added the ability for users to set an "Auto Accept" price for listings through Mascot. When you go to list an item for sale, check off eBay as a marketplace, you will see an "Auto Accept Price" column right next to "Minimum Offer Price." You can set a price at which you'd like any offers at or above the Auto Accept Price to be automatically accepted.
You can also pull in "Auto Accept Price" as a Column Header in the Collections screen. To locate this, click "Columns" and check off "Auto Accept Price", then drag and drop it wherever you'd like to see this column appear in the dashboard.
