You'll want to nip down to Virgin Mobile refurbished store if you want this great bargain!
The price listed is £54.99, but if you already have a Virgin mobile sim card - log in and you ll get £10 off the price. This makes it £44.99. Quidco now gives away £8 for a Virgin Mobile purchase so this effectively makes it £36.99!
It's a refurbished product, but still great value! Hurry! :)
