Amazon is kicking off today’s Prime Day a bit early. Although its annual sale technically begins at 12 PM PT / 3 PM ET this afternoon, it put its own devices on sale 12 hours early. The company is marking down its Alexa-enabled products like Echo, Fire TV, and Fire tablets, as well as its home security products like the Cloud Cam and more recently acquired Ring Video Doorbell. The retailer has also released a list of Prime Day deals, which encompasses other Amazon product discounts, as well as those from other manufacturers. This year’s Prime Day promises to be the largest yet, both in terms of the number of deals and the length of the sale itself, which has been stretched to 36 hours.
