Surface fans in the UK can save some money on their next device thanks to a new promotion. People in the UK can trade in old laptops to receive up to £500 towards a Surface Pro X, Surface Pro 7, or Surface Laptop 3. To participate in the promotion, you have to preorder a Surface device before October 22, 2019.

A Microsoft webpage breaks down the promotion and also lists details on how much money different devices are worth. Any working laptop up to five years old is worth £100. Any MacBook up to two years old is worth £500. Several Surface devices are worth £500, including any Surface Pro 6, any Surface Laptop 2, and any Surface Book 2.
