The overall performance for your 7-day Deals and Lightning Deals can be found in the Manage Deals page in Seller Central.
Click View on the specific Deal to see performance for each SKU in the deal. The following metrics will be provided to you in the Product Details and Pricing section of your deal:
Units sold: The number of deal units sold during the deal
Items waitlisted: The number of items that the customers added to a waitlist after a deal sells out. A high number of items waitlisted suggests that you could have sold more deal units than the Quantity for Deal that was entered for the SKU
Deal revenue: Ordered product sales (Units Sold x Deal Price) for that SKU
Total deal revenue: Ordered product sales for all SKUs that participated in the deal
Note: Your sales data might take up to two hours to become available after the deal ends.
