You can usually get train fares for around a tenner each way, which usually go on sale about twelve weeks before the day of travel; you'll need to register an account (no charge) on the relevant train co website (Virgin in this case?) and there's usually an option to get an automated email informing you when the tickets go on sale for the date you want to travel.
Or if going from London to Manchester and coming back via Leeds you can probably still get a tenner each way and book via any train co website for the same price. I get all my tickets through East Coast as it's the first one I registered with. You may get a couple of quid cheaper by going through each different website, but usually you can get all your cheap tickets for the lowest price via any one site.
