Carphone Warehouse started a deal today where you get Sky Fibre up to 50MBPS for £18. That includes line rental. I cannot see it on the website.
They are also doing Beats EP for £44.99 (Half Price) on any PAYG handset. Cheapest Handset is free with £10 top up i'm sure. I've searched for the deal on HUKD and cannot find a similar one.
