You will also be charged around £5 for delivery via UPS. It does not mention this on the offer details nor does it mention it on the Terms & Conditions.
Just thought I should point it out before you call!
Also. It states on the web offer that if purchasing in store at Zavvi you will need a copy of your latest VirginMedia bill. I called my local store in Glasgow Fort and was told that they would not be doing it on that basis. They stated that they required a mailing letter specifically offering this to the customer and that the copy of the bill would not be accepted.
So call first to make sure! Cheers.
