Microsoft has launched a trade-in program for those looking to get a new Surface Pro 4. By handing over your old MacBook, PC, or Surface, you can receive up to $650 towards a new Surface. Your device doesn't have to be in working condition, but a working device is worth more.

The trade ins can be completed online or in a Microsoft store. If the trade is completed online, Microsoft will estimate your device's value before you send it in for an exact amount.

When a trade is completed, you'll receive a promo code that can be used to reduce the cost of a new Surface Pro 4.
