You might want to hold on for a week or two...
VM have recently suspended
a special offer that effectively offered their own version of a popular wireless router to many customers for nothing. As in, FREE.
It was so popular that they've had to hold off further orders but it could well be back soon.
If you're too impatient to wait that long, you can order the same router from VM for £40.
(NB: The £40 is to supply and support the router, not to purchase it -- it remains the property of VM.)
The only advantage of this deal is that if you have a problem, eg. you can't get it working correctly, it'll be up to Tech Support to show you how to fix it.
