Cyber Monday is the online equivalent of Black Friday, the post-Thanksgiving shopathon that puts our January sales to shame. With huge deals at some of our favourite retailers all the over the web, the event has quickly crossed the pond with plenty of UK retailers getting in on the act and offering percentage discounts and special offers on purchases for one day only. And of course we have the skinny on some of the best deals.
