Samsung is currently running a promo where-in those trading-in their old phone will get up to $350 discount on the Galaxy S8/S8+. The deal is available on AT&T, Verizon, and US Cellular variants of the flagship duo, as well as unlocked models.
The minimum trade-in value is $200, but the figure goes up to $350 depending on the device you’re trading in – Galaxy Note5 ($300), Galaxy S7 ($300), and Galaxy S7 edge ($350). It’s worth mentioning that unlocked Galaxy S8/S8+ models already have a $100 discount on them, so you save even more in that case.
Needless to say, the device you’re trading-in should be in a good condition, else the discount comes down to just $25.
