If you’re eligible you will see a ‘Successfully Signed Up’ message appear once you click the button.
Then, you need to top up your Amazon Gift Card balance by at least £80. You can do that by clicking here.
You will then receive a confirmation email and the reward will be processed within a few minutes after completing your order.
If you want to check out your Amazon Gift Card balance you can do so on this page.
