Unsurprisingly, Amazon has reserved a lot of really good deals for itself: Select devices across its Echo, Fire, Kindle, Blink, and eero brands are on sale for up to 58% off on Prime Big Deal Days, including dirt-cheap Fire tablets and Echo smart speakers that come with free smart bulbs. Prime members can snag four free months of Amazon Music Unlimited, three free months of Kindle Unlimited, and a $10 discount on one GrubHub order of $15 or more; don't forget to use the coupon code PRIME10 at checkout. Beyond that, we've seen a slew of TVs, laptops, tablets, headphones, and fitness trackers on sale on Amazon. Of note, that includes new all-time lows across the Apple lineup: Several MacBooks, the latest iPads, and the all-new AirPods Max with USB-C have never been cheaper on Amazon before today. Extra-deep discounts on robot vacuums are also making appearances, to the tune of up to $850 off.
