Not sure if this has been mentioned already (apologies if it has) but BT seem to have pulled a fast one with their upgrades. The BT Yahoo product which was 1Mbit/30GB is now 2Mbit/15GBit and is currently priced at £26.99 but only for 3 months then goes back to £29.99. If u want 2Mbit/30GB you've got to wait until the end of March for this to be launched but what will the price be? Probably close to £35.
So BT's broadband prices haven't remained the same as they stated instead they've tried to disguise it with a 3 month price reduction!
