Aside from aggressively lurking on Amazon's dedicated Prime Day page (and reading our coverage of the sale), there are several ways to ensure you don't miss out on a great deal: Sign up for Amazon's invite-only deals. Organize your Amazon Wish List. Amazon's virtual shopping list feature puts all of your must-haves in one convenient spot so you can see which ones are on sale at a glance (instead of flipping between links and tabs). Check out Mashable's guide to "wishlisting" for more intel. Download the Amazon Shopping mobile app. The app features a Prime Day event page where you can set deal alerts for your recent Amazon searches and views; you'll get pinged with a push notification as soon as an offer goes live. Take advantage of Alexa's advanced deal alerts feature. Amazon's virtual assistant can notify you of a sale on an item in your Wish List, Shopping Cart, or "Saved for Later" queue up to 24 hours before it goes live. Enable the feature on a newer-gen Echo smart speaker, and you'll see its light ring turn yellow (or you'll get a pop-up alert) whenever an item you've saved has a discount in the pipeline. You can then ask for more information about the deal, set a reminder for when it's available, and even give Alexa permission to order it for you using your default payment info when the time comes.
