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). Reference prices are displayed in several places, including on product detail pages and in search results for your products, to show savings to customers.
If you do not have a ready-to-provide List Price, a possible value could be the first price at which you offered the product. If Amazon cannot verify your List Price, we might not use it.
A Was Price is automatically computed and changes over time. The Was Price is determined using the 90-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.
For more information on how to add list prices or what values to provide, go to Show a reference price on your products by proving a List Price.
