In many product categories, you have the option of supplying a reference price, such as a list price (for example, a Manufacturer's Suggested Retail Price or MSRP), or a price that is struck through when you're offering a discount on your products (for example, a sale price). These reference prices may be displayed in several places, including the product detail pages and search results for your products, to show savings to our customers.
If you don't have a list price that meets these criteria, please leave the field blank when adding a new product. If Amazon cannot verify the list price you provide, we may not use it.
A Was price may display in several places, including the product detail page, the deals page, and search results for your products, to show savings to customers. The Was price is determined using the 30-day median price paid by customers for the product on Amazon. We exclude prices paid by customers for the product during a limited time deal.
