I used to travel to London about five or six times a year until I was made
redundant recently.

When in London, I would add credit online to my PAYG Oyster account prior to
leaving home (Kirkcaldy).

While in London, I would just keep a check on my balance and top-up at a
ticket machine if/when required.

The thing is, I have managed to fit in a trip to London in a few weeks, and
don't want to leave unnecessary funds on my card which I probably won't use
again for a long time.

Now comes the question(s):- I have looked at the PAYG Auto Top-up page (when
balance falls below 5GBP) for my account, and it is only offering a
*minimum* top-up of twenty pounds. I wouldn't even add that much if I was
still in work. Is there no way to set up ATU for less than this amount?

Regards,

Alan
