Microsoft is starting to roll out a pilot feature to Cortana that could save you some change while shopping in Edge. Currently rolling out to everyone on the Windows 10 Creators Update, the feature lets Cortana help you find cheaper prices on items you're shopping for by automatically comparing retailers across the web.
The way the feature works is fairly simple. While you're shopping online, a Cortana display notification may pop up in the address bar alerting you that it has found other retailers with cheaper prices for the item you're looking at. Click on the Cortana icon, and the right pane will open up to show you the various options.
This is similar to another online shopping feature available in Edge, whereby Cortana will offer up discount coupons for certain items on a given site. It's not hard to imagine that most will find the new comparison shopping feature a little handier, however.
Currently, this is only making its way to users in the U.S. Further, the feature only works with a total of 14 retailers at this time, but some big names like Amazon, eBay, and Home Depot are on board.
