Deal: Unlocked Samsung Galaxy S8+ costs just $690 on eBay
The conditions of the deal/s may have changed since the initial publishing of this post.
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.
