Microsoft continues to make server-side updates to its Cortana digital assistant. The latest example is rolling out now for Windows 10 owners who use the Microsoft Edge browser, and it will offer alerts, via Cortana, on new coupons from a number of online retailers.

Microsoft says:

"This new feature leverages Cortana's functionality to notify you of the best coupons Cortana can find for a retailer without you ever needing to leave the retailer's site. We are just beginning to roll this out to get feedback. This initial release includes coupons for retailers like Staples, Macy's and Best Buy. We will be increasing availability and the number of retailers we support in the months ahead through our partnership with Shopular, a leading coupon provider."
