Amazon now has a new Automated Pricing Tool, which will automatically adjust your price in real time.
"In Amazon Seller Central you choose the rules and the tool responds 24/7. Select your products, customize your parameters and let Amazon execute your pricing strategy and improve your chances of becoming the Featured Offer."
Shopify merchants are now able to view and control the application of these rules in Marketplace Connect.
This is available on Single Edit, Bulk Edit and Attribute mapping.
