Hi eb154,
Thanks for your post and questions surrounding adding the Stream box.
Since posting I can see you've spoken to the team and they have ordered the Stream box for you and this will be delivered shortly.
The team would have given any discounts you were entitled to at the time but it's worth noting that when adding new equipment, there usually is a £35 activation fee so this would be right.
Please keep us posted on how you find the Stream service.
Thanks,
