Amazon’s Prime Exclusive Phones program is a real steal, but it comes with a catch. If you’re a member of the retailer’s $100-a-year Prime program and agree to let Amazon stick advertisements on your smartphone’s lock screen, you can nab a device for a discount. The lineup has grown considerably over the year, and it’s finally getting a flagship smartphone in the roster.

The discounts are nothing to shake a stick at. Here’s every device that’s currently available through Amazon Prime Exclusive Phones:

LG

LG G6

The LG G6 is the latest top-tier phone to make it to the Amazon Prime Exclusive program, and that’s a pretty big deal. It’s the first flagship smartphone that initially cost $650 at launch that’s now on the list. While the Qualcomm Snapdragon 821 processor is from last year, it offers plenty of juice most people would need. It comes with 4GB of RAM, 32G of storage, and the nice big 5.7-inch display has a 2,880 x 1,440 pixel resolution and it rocks the popular bezel-less smartphone trend. So how much will it cost? Through the Amazon Prime Exclusive program it’ll set you back $400. The phone comes unlocked, and it’s compatible with all major U.S. carriers.

LG G6 Plus

The G6’s big brother is also available through Amazon’s program. The G6 Plus is very similar to the standard G6, but it offers a hefty 128GB of storage and a 32-bit Hi-Fi Quad DAC to keep those audiophiles happy with the audio quality on their phone. It’ll cost a little extra at $500.

LG Q6

If you want a slightly more budget-minded phone, then the LG Q6 might be the right device for you. The phone features a design similar to the G6, but with a less powerful Qualcomm Snapdragon 425 processor coupled with 3GB of RAM and 32GB of storage. The rear-facing camera sits in at 13-megapixels, with the front-facing cam offering a 5-megapixel sensor. The Q6 is compatible with AT&T and T-Mobile, and costs $230.

LG X Charge

As the name suggests, the LG X Charge is built for battery life. The capacity sits in at a hefty 4,500mAh and it has fast-charging capabilities, which is good news for those that use their phone heavily or forget to charge. It also has 2GB of RAM, 16GB of storage, a 13-megapixel rear-facing camera, and a 5-megapixel front-facing cam. It’s compatible on AT&T, Sprint, and T-Mobile, and costs $200 on Amazon.

Nokia

Nokia 6

The Nokia 6, HMD Global’s new Nokia-branded smartphone, is $180 ($50 off the full retail price). It features a polished aluminum design and a 5.5-inch Full HD display, rounded out by a Qualcomm Snapdragon 430 processor (paired with 3GB of RAM and 32GB of internal storage), a 16-megapixel rear camera and 8-megapixel front camera, dual Dolby Atmos speakers, and a fingerprint sensor. It’s compatible with AT&T and T-Mobile.

Alcatel

Alcatel Idol 5S

Alcatel’s Idol 5S, normally $280, retails for $200 — one of the largest discounts ever offered for a Prime Exclusive Phone. It packs a 2.5D curved glass design, a 5.2-inch Full HD display, a 12-megapixel rear camera and 8-megapixel front camera, a fingerprint sensor, and 32GB of internal storage (expandable up to 256GB via MicroSD card).

Alcatel A50

The Alcatel A50, normally $150, is $100 on Prime Exclusive Phones. It boasts a 5.2-inch HD display, a 13-megapixel rear camera and 5-megapixel front camera, 2GB of RAM, and 16GB of internal storage. Uniquely, the A50 ships bundled with the LightUp Snapbak LED cover, a light-up case that illuminates when calls, messages, e-mails, and more come in.

Alcatel A30

The Alcatel A30, which starts at $60 on Prime Exclusive Phones ($40 off the full retail price), isn’t as compromising as its low price point suggests. It’s got a 5-inch HD screen, a Qualcomm Snapdragon 210, 2GB of RAM, and a 32GB of internal storage, plus a pair of cameras (8-megapixel on the rear and a 5-megapixel selfie camera), and a reinforced protective glass casing. It works with AT&T and T-Mobile, and it’ll support Verizon after an update.

Alcatel A30 Plus

The Alcatel A30 Plus is available $80 for Prime members ($50 off the full retail price). It features a metallic silver finish and a 5.5-inch HD display, plus a 13-megapixel rear camera and 5-megapixel front camera, 2GB of RAM and 16GB of internal memory (up to 32GB via MicroSD card), and a 3,000mAh battery. It’s compatible with AT&T and T-Mobile, with support for Verizon to come after an update this summer.

Motorola

Motorola Moto X4

The Moto X4, one of Motorola’s newest flagships, starts at $330 ($70 off MSRP) for Amazon Prime members. In exchange for your hard-earned cash, you get a 5.2-inch Full HD screen (1,920 x 1,080 pixels), an octa-core Snapdragon 630 processor paired with 3GB of RAM, 32GB of storage (with an expandable MicroSD card slot), and a 3,000mAh battery. But that is not all. The body’s IP68 rated, meaning it’s water resistant in up to to 5 feet of water for 30 minutes, and houses a dual 12-megapixel cameras on the rear and an 8-megapixel front camera. The Moto X4’s ace in the hole, though, is its broad network compatibility: It works with Verizon, AT&T, T-Mobile, and Sprint.

Motorola Moto E4

Motorola’s Moto E4 is $100 for Prime members ($30 off the full retail price). It’s got a compact metal design, a 5-inch 720p HD display, a respectable pair of cameras (8-megapixel rear and 5-megapixel front), a fingerprint sensor and 2,800mAh battery, and 2GB of RAM paired with 16GB of internal storage. It works with AT&T, T-Mobile, Sprint, and Verizon.

Motorola Moto E4 Plus

Amazon has the Moto E4 Plus on offer too. For $140 ($40 off the full retail price) you get a 5.5-inch 720p HD screen, two pretty good cameras (13-megapixel on the rear and a 5-megapixel on the front), and 16GB of storage. Under the hood is a quad-core processor, 3GB of RAM, a massive 5,000mAh battery, and radios that work with AT&T, T-Mobile, Sprint, and Verizon.

Motorola Moto G5 Plus

If the Moto E4 and E4 Plus don’t float your boat, consider the Moto G5 Plus. It costs $185 ($45 off the full retail price) and has a 5.2-inch IPS LCD with a resolution of 1,920 x 1,080 pixels, a capable pair of cameras (12-megapixel rear and 5-megapixel front), and 32GB of storage. Keeping things humming is an octa-core Qualcomm Snapdragon 625 processor paired with 3GB of RAM, and a 3,000mAh battery that lasts a full day on a charge.

What are Amazon Prime Exclusive phones?

A word of warning before you pull the trigger on an Amazon Prime exclusive phone: You’ll have to acquiesce to retailer’s advertisements. Amazon reserves the right to put “personalized” offers and ads — including deals and product recommendations — on Prime Exclusive Phones’ lock screens.

That said, Amazon’s devices aren’t without little conveniences. They ship automatically signed into Amazon’s services and apps, including (but not limited to) Prime Video, Prime Music, Amazon’s cloud storage service Prime Photos, and ebook lending program Prime Reading. They also come with Prime’s other benefits, including one free ebook every month, two-day shipping on 50 million items, one-day shipping and same-day shipping in more than 5,000 cities and towns, and more.

It’s not exactly surprising, then, that Prime Exclusive Phones have been a resounding success. According to Amazon, the discounted devices have been “constantly featured” in the top five best-selling unlocked phones list on Amazon and among the “top rated” unlocked smartphones on Amazon.com.
