Are you sure on that Vodafone deal @piratepete108? Their website says from £30 a month on the tier that offer all their speeds, so I'd guess that is for the slower speeds. The cheapest I can see the 900Mbps offering is £60 a month. I'm not sure if that is via the Openreach network either, as it says it's not available to me, though FTTP is and other providers can supply me that, though that might be because of the interconnects that Vodafone have at my Headend.
Shell have announced their FTTP prices on 18 month contracts as follows:
100mbps down, 20mbps up £30.99
Also out of interest their FTTC prices are the same across both speed profiles 40/1 and 80/20, as they are with Now Tv broadband
