Best Galaxy S9 and S9+ Deals for October 2018


New rumors surrounding the Samsung Galaxy S10 and the recent release of the Apple iPhone XS and Google Pixel 3 have taken attention away from the Samsung Galaxy S9 and S9+.

But that's good news for shoppers because retailers are offering some of the best deals we've seen on Samsung's aging flagships. Through November 3, when you upgrade to a Galaxy S9, S9+, or Note 9 — Samsung will double the trade-in value of your old phone. Trade-in an iPhone X or iPhone 8 Plus to get the full $600 or get $550 when you trade-in an iPhone 8 or $500 for a Galaxy Note 8. 

To redeem this deal, head over to Samsung or Amazon and follow the trade-in instructions. This deal is only valid for purchases made through November 3.

If you don't have a phone to trade in, the best price we've seen for an unlocked S9 has been $559 — a now-expired, 24-hour deal that came courtesy of Newegg. But bargain shoppers shouldn't worry because there are other excellent deals available at the moment.

Amazon, for instance, has the Unlocked Galaxy S9 for $594.18 ($125 off) and the Unlocked Galaxy S9+ for $739.99 ($100 off). The limited-time sale is the best we've seen from Amazon in recent months. (Samsung has the same prices for the unlocked Galaxy S9 and the unlocked Galaxy S9+).

How does that stack up with other offers? Here are the best deals for the Galaxy S9 and S9+ so far.

Best Buy

Best Buy's best Galaxy deals are currently found with AT&T and Sprint. AT&T customers can take advantage of Best Buy's Galaxy S9/S9+ BOGO promo (requires at least one new line of activation). Meanwhile, Sprint customers can get the S9 for $9/month or the S9+ for $14/month.


Walmart is taking $150 off the S9 and S9+ when you purchase the phone in-store and sign up for a installment agreement with AT&T or Verizon. (Scroll to the bottom of the page and click on the "shop now" button to see details). 


Verizon is taking $100 off the Galaxy S9 and S9+ when you upgrade from an older phone or they'll take $300 off when you switch from a competing carrier or add a new line.  A trade-in is required in both cases.


At AT&T, buy a Galaxy S9 at full price ($789.99) on AT&T's Next installment plan (30 months at $26.34/mo.) or AT&T Next Every Year (24 months at $32.92/mo.) and get a second S9 for free. Alternatively, you'll get $790 off a second S9+. However, keep in mind the device will be "free" in the form of bill credits (applied to your account). So you'll need to purchase both devices at full price upfront. The deal also applies to the Note 9.

If it's the lowest monthly price you're after, Sprint has the S9 for $9/month (normally $33/month) or the S9+ at $14/month (normally $38/month). Both require an 18-month Spring Flex lease.


The UnCarrier Network currently has a BOGO offer on the S9 and S9+. That means you'll pay $720 for the S9 ($30/month over 24 months) or $840 for the S9+ ($30/month over 24 months + a $120 down payment) and get the second phone for free via 24 monthly bill credits. Just keep in mind that the offer requires that you open a new line of service.

Prepaid Carriers

The prepaid carriers are also getting in on the S9 deals. For the absolute lowest prepaid price, Boost has the S9 for $699.99.

StraightTalk is offering the S9 for $699.99 and the S9+ for $829.99. Just keep in mind that in our tests StraightTalk had the slowest LTE speed and provided one of the worst customer service experiences we've gone through.

MetroPCS also has the S9 for $599, which is the best price you'll find from any carrier. (They currently don't offer the S9+).
