Smartphone upgrades don't have to break the bank, even if you're shopping for high-end, unlocked models. Check out our roundup of the week's best phone deals to see the Samsung Galaxy Note 8 fall under $700 for the first time. Refurb Unlocked Apple iPhone 6s Plus 64GB Smartphone Store: eBay Price: $264.99 Shipping: Free shipping Lowest By: $75 The best way to save on Apple's pricey gadgets is to shop for previous-generation iPhones, especially if you're willing to shop refurbished units. This Editors' Choice offer on the 6s 64GB model is a prime example, as it's fallen by a massive $135 since October to its best-ever price. It's even selling for around $75 less than any other refurb today! Note: No warranty information is provided. Be aware that this phone may have cosmetic blemishes, which is the downside of shopping such cheap models. Unlocked Samsung Galaxy Note 8 64GB Phone Store: eBay Price: $689.99 Shipping: Free shipping Lowest By: $83 Upon its release last September, the Galaxy Note 8 was highly reviewed, and CNET even called the model out as being "the most feature-rich Android phone you can buy." And although reviews weren't perfect (concerns over the fingerprint reader and camera's portrait mode were highlighted), the only major issue noted was its high price. But the phone's now fallen to under $700 for the first time, which is a healthy $239 drop since its release, and is one of our Editors' Choice deals. This hybrid dual-SIM phone features an Exynos 8895 8-core CPU (2.3GHz quad-core and 1.7GHz quad-core CPUs, 6.3" 2960x1440 Super AMOLED touchscreen, 6GB RAM, 64GB storage, 802.11ac wireless and Bluetooth 5.0, dual 12MP cameras, and Android 7.1 OS (Nougat). Google Pixel 2 XL 64GB Smartphone Bundle Store: Verizon Wireless Price: $549.84 Shipping: Free shipping Lowest By: $409 Expiration: May 30 With the Pixel 3 series rumored for release in October, we're slowly starting to see the price come down on the last generation of Google phones, and this Verizon bundle is the best deal so far this week — and one of our Editors' Choice picks. Not only will you get the phone at an incredibly low price ($22.91 a month for 24 months), but you'll get a Google Home Mini, Chromecast, and two months of YouTube TV all for free. Altogether, that yields a huge savings of $409. The phone features a Qualcomm MSM8998 Snapdragon 835 2.35GHz 8-core CPU, 6" 2880x1440 pOLED touchscreen, 4GB RAM and 64GB storage, 12.2MP rear camera (with 4K video recording) and 8MP front camera, 802.11ac wireless & Bluetooth 5.0, USB 3.1 Type-C, and Android 8.0 (Oreo). Note: You'll receive your savings as a monthly bill credit. The Home Mini and Chromecast will be mailed to you within three to four weeks of purchase. Be sure to cancel your YouTube TV subscription before your free two months end, or you'll be billed $40 a month for each subsequent month. Motorola Moto E4 Plus 16GB Smartphone for Boost Mobile Store: Boost Mobile Price: $79.99 Shipping: Free shipping Lowest By: $20 For those on a leaner budget, this prepaid Moto E4 Plus is an almost frill-free phone, but with one exception: a seriously impressive battery life. According to TechRadar, you'll get up to two days of life out of its hefty 5,000mAh battery. So if you're more interested in long life than high specs, nab the prepaid phone via Boost while it's at $20 less than any other carriers' best deal. It features a Snapdragon 427 1.4GHz quad-core CPU, 5.5" 1280x720 touchscreen, 2GB RAM and 16GB storage, 13MP rear camera and 5MP front camera, and Android 7.1 OS (Nougat). Unlocked Samsung Galaxy S9 64GB Smartphone Store: eBay Price: $649 Shipping: Free shipping Lowest By: $21 We may have predicted that May would be the best time to splurge on Samsung's flagship phone, but this deal on the Galaxy S9 is tempting. It's dropped by another few bucks over the weekend to an impressive all-time low, and is currently available via eBay for around $21 less than any other store. Similar in features and design to the S8, it does include a better-placed fingerprint reader and a celebrated upgrade to a dual aperture 12MP rear camera (which can switch between f2.4 and f1.5).
