Someone found a way to directly access the Barclays special price offered to customers. No connection with Barclays bank needed. dare say this will stop working sometime soon but if you want good antivirus at a knock down price of £6.99 for 5 devices (pc phone etc)..

If you have a Quidco account you can get 40% cashback too. Go to quidco then kaspersky and add something full price to your basket. Now go to the hotdeals deal link and click it. Check the basket again on your quidco kaspersky and it will have 2 items. remove the full price one and check out with £6.99.
