BOGO Galaxy S9 at T-Mobile

"You can buy a Galaxy S9, Galaxy S9+, or Galaxy S8 Active and get $720 off a second Galaxy S9, S9+, or S8 Active via bill credits. Pricing on the S9 is $720, so a second S9 would be free, but the S9+ is $840 and the S8 Active is $850, so customers that choose those devices would still owe a bit for them."- Alex Wagner

"Customers who take advantage of this offer must purchase both of their devices on a 24-month Equipment Installment Plan. The required down payment ($120 for S9+, $130 for S8 Active) and any applicable device taxes are also required at the time of purchase."- Alex Wagner
