Postage stamps going up in April

I still think it's cheap to send a letter! The way I look at it is that I need to find someone to get me a letter from one end of the country to the opposite end in a couple of days?
Who would like to take this letter for me for a pittance? (under a couple of quid) 

Taxi driver, pony express,bus driver, train driver, aircraft pilot, I think not?   This is where Royal Mail steps in.
