@WOWBOY. Ironically, Ryanair has just stopped charging any "invisible" unavoidable fees during the booking process. Actually you can only become a "victim" of unwanted insurance or priority boarding fees (or alike) if you are not smart enough during the booking process (if you don't know how and when to say no). The online check-in fee is enclosed in the final price from the very beginning, at least while booking directly with them, so you have already payed it. Again, while booking directly.
