How much do you pay for your SKY broadband ?

hi , i mean the total bill every quarter or if you pay monthly , ie:including the line rental and broadband, just looking to compare it to bt , any package would do as the websites do not make it clear grrrr, why can they not just put it in plain n simple terms without the extra hidden costs ie:after 3 months the bill goes SKY high pardon the pun lol
