Deal: Unlocked Samsung Galaxy S8+ costs just $690 on eBay

The Galaxy S8+ is available in the United States for more than a month now, so its price remains the same at just about every major carrier in the country. Of course, T-Mobile is running a BOGO (buy one get one free) deal on the smartphone, and it's even cut the outright price of the phone from $850 to $780, but that's about all you get if you're looking for a bargain.

Well, it looks like one eBay seller offers a much better deal on the Samsung Galaxy S8+, especially if you don't want to take on T-Mobile's BOGO offer. The unlocked version of the flagship is now available for purchase on eBay for just $690, nearly 20% less than its upfront price.

The only caveat is the phone won't work on CDMA networks, which means you won't be able to use it on Boost, Sprint, and Verizon. On the bright side, the smartphone features dual-SIM support, and you can certainly use it on AT&T and T-Mobile.

It's also worth noting the smartphone is available in limited quantities, and just three color options are still up for sale: Black, Gold, and Gray. The Blue and Silver versions are now sold out on eBay, so you might want to hurry if you want to take on this deal.
