These were previously only free for Sky movies customers and cost £21.95 otherwise, though I know there was a previous deal for £9.99. But you can't get better than free, and you don't even need to call Sky to get it - just login and click!
To say thanks for being a Sky customer, you can now register to claim a free wireless connector to bring our On Demand service to your TV.
If you have a compatible black Sky+HD box and a broadband connection, and you have never connected to On Demand, click the Claim Now button.
Then, enter your Sky username and password when asked. (Need help with your username or password?)
