Sprint 2 for 1 Samsung Galaxy S9 and S9+ this weekend
Sprint and Samsung have a new promotion available only this weekend from March 24th to March 25th in every Sprint Store.
If you lease the new Galaxy S9 ($33 a month) or Galaxy S9+ ($38 a month) with Sprint Flex you receive another Galaxy S9 free, after $33 a month credit applied in 2 bills (18 month required).
For existing customers the offer is available with 2 new lines or 1 new line and 1 upgrade. This offer can be applied with Galaxy Forever, so you automatically upgrade to the newest Galaxy every year.
Also, as usually happens, if you cancel early you will have to pay the remaining balance due.
