Yes but how do I book a ticket from A-B on Day1, then A-B on day 2 as well, or is there no such ticket for this? I know I could get a 7 day 'season ticket', so I was wondering if something like that was available for 2 days.
The shortest 'season' ticket I could ever get was for 7 days. I reckon you'll need two returns.
Here's a site to help break the journey which can prove to be cheaper: http://www.splityourticket.co.uk/
 Erm... Isn't that the whole reason you are on that site in the first place?
If I go to london then home one day, and then the next day I do the same thing are there any special tickets I can get or do I have to get two separate returns?
