The best thing to do is to contact the airfield operator in advance and make the appropriate arangements i.e. you pay in advance by credit card or you stop to pay or they send the bill.
The one time this can account for a great saving in the UK is if one wants to get an airport like Glasgow in the log book.
Such airports are required by law to basically charge every user on a relatively equal basis. Thus landing fees are not overly expensive. What makes a visit expensive is the handling fee which you must pay thus pushing something like a £15 landing fee to £40+ including mandatory handling.
If you ring in advance and pay for a landing over the phone by credit card then you pay the much smaller ammount and can either touch and go or land, taxi back to the hold and depart again. You could even possibly change crew!
I have done it in the past with absolutely no problem
