Certianly owning your own strip makes things alot cheaper (in the UK or non FAA land).
On the Isle of Man I use Andreas which is owned by a friend of mine, so It doesnt cost me a bean. At Filton if I fly the club plane then I don't pay landing or parking fee's. All this month I have borrrowed my mates plane which has cost a fortune in landing fees and parking fees.
To keep fuel costs down I have an Air BP account so I get 100LL for about £1.07 per litre. It is definatley worth getting fuel accounts as you do pay slightly less and you can pay monthly (as in settle the account every month).
