Recently I noticed Google is showing a carousel above the products to filter based on price. More specifically, Google will allow you to filter product search results by clicking on the price ranges.
The price filter is located above the product carousel, and users can filter out the products based on the price.
About this result: As per Google, This is info that Google gathered about products available to buy. Prices below their 90-day average from this retailer are shown as price drops.
