T-Mobile is offering a buy one, get one free sale on the Note 8 — with a few caveats

There’s no way around the fact that at around $930, Samsung’s new Galaxy Note 8 is an expensive phone. But if you’re a T-Mobile customer looking to pick up Samsung’s latest flagship, you might be able to get a second phone free — if you meet T-Mobile’s very specific set of requirements to qualify for the deal.

Here’s what you need to do to qualify: the promo requires you preorder two Galaxy Note 8s from T-Mobile through its equipment installment plan, which requires a $210 deposit for each device, for a total $420 down payment upfront. Then, you must sign up for a new line of service to activate on the second device. This will qualify you to receive a rebate for the cost of the second device, meaning you will still have to pay for the entire thing but will get a check refunding the cost at a later date. It costs $30 a month for each Note 8, which you’ll owe T-Mobile for 24 months.

And lest you think that you can just activate a new line, grab your free phone, and run, T-Mobile is being very clear upfront that early cancellation will result in you getting billed the full price of the second phone.

Still, if you’re planning on getting a Note 8 and have someone else who’d like to join up on your T-Mobile plan, it’s hard to call a discounted $930 smartphone a bad deal.
