My first post so please be gentle!!
Found this really good deal whereby you can add unlimited bus travel to your train ticket from £1 per day. Apparently it's available in 195 UK towns and cities.
I found it on the One Railway site, am off to Norwich and as buses are extortionately priced there (£2 for a 1 way journey last time I went) it'll be quite a saving! Don't know how much buses are in other cities but hopefully it'll save someone some money.
