Sprint is knocking $200 off the Galaxy S6 or the Galaxy Note 5 when you trade in your old (but working) smartphone.

The offer reduces the price of the Galaxy S6 to just $9.76 a month, and the Note 5 to just $16.67 a month over 24 months. It can also be combined with Sprint’s half price deal for switchers coming from AT&T, T-Mobile, or Verizon.

Sprint says the $200 discount is “guaranteed” when you trade in your old device, so your local store won’t offer you less than that. It should be noted, however, that your device must at least be working, and should not be leased.

The discount is only good against a Galaxy S6 or Galaxy Note 5. We recommend you take the latter what with the Galaxy S7 right around the corner, but if you don’t like larger smartphones, the Galaxy S6 will still serve you well for the next two years.

Sprint says you can get this discount in stores today, and online or over the phone later this week.
