Retailer ratings on your product pages
Your product pages now show what shoppers rated each product at Amazon, eBay and Walmart. Under the price, a short list shows your own review first, then each retailer and your store's reviews, with a logo, score and count. A More reviews section further down gives each source in full, with when it was checked and a link to the retailer.
All sources are on by default except the eBay seller score. Switch each one in Store > Settings > Products > Reviews on product pages.
