Amazon Prime subscribers in the United States who also have Echo smart speakers can enable deal alerts to receive notifications 24 hours before discounts go live and even have your Alexa purchase these items for you. How to set up Alexa deal alertsFirst, open the Amazon Shopping app or go to Amazon’s website via browser and add products you want alerts for to your Wish List, your Shopping Cart, or a Saved for Later list. This ensures you’ll receive notifications for items that appear in your shopping activity. You can also ask, “Alexa, what are my notifications?” to hear a list of deals it has compiled thus far.
