Apple’s brand new iPhone 6s has the same price as its predecessor, starting at $649 for the 16GB version. T-Mobile and Sprint have already figured out ways of making the new iPhone even more affordable, with installment pricing going as low as $1/month for those customers who qualify. But there’s one more interesting iPhone 6s offer that Apple fans should know about.

DON’T MISS: 10 killer iPhone 6s tricks you need to know

Boost Mobile is ready to sell you a 16GB Space Grey iPhone 6s for just $449.99 with free shipping. That’s the price you get after receiving an instant discount of $100 while an extra $100 off is available with this coupon code: B6677847.

The good news is that there’s no contract to sign, as Boost Mobile’s offer targets prepay customers. However, as 9to5Mac notes, there is one downside to this: the iPhone 6s is locked to Boost Mobile. That means you can’t just switch carriers on a whim, and you’d have to unlock the device to use it on a different network. Furthermore, the only color option or storage version that you can purchase for $200 off is the 16GB Space Grey option.

Boost Mobile’s prepaid plans start at $35 per month, including unlimited data, talk and text messages.
