Not only does that Audible subscription include an entire month of access to its library of audiobooks, but you'll also be allowed to pick two audiobooks to own permanently, regardless of when you cancel your subscription.
Speaking of, you can cancel that subscription anytime within your first free month of Audible to not pay a single cent, even while keeping that £10 gift voucher, which basically amounts to making money for approximately 90 seconds of your time making sure you click the right buttons.
