cheapest rail ticket

jota

I am very new to this site, I am looking for help in a journey I'll be undertaking by rail from paisley(5 miles from glasgow) to bognor regis on the south coast,outward on the fri 5th aug and return mon 8th aug, I've looked at getting the sleeper to euston on thurs night, arr fri morn, similarly sleeper on mon night which would give me the afternoon in london for a look about, sleeper fares start at £19 each way if you can get them, but are only very limited availability, and are supposed to go on sale 12wks in advance, this is my first trip anywhere in some 10 years due to ill health, so any advice on how to proceed and who/when to book with would be very gratefully received, thank you for reading,
Joe Taylor.

You are too early for your dates.
See here for booking horizons.

I know nothing about the sleepers, but London Victoria to Bognor Regis can be done for £3.75 each way using Advance Singles booked via Southern Railway's website.
