It's not very difficult, you just have to be careful when filling the forms, they are a bit confusing...

For example to refuse the travel insurance policy you must choose that you don't want it in the country selection box...

Personally while I find it irritating, I find godaddy much worse and since unlike Ryanair they have cheap competitors without dark pattern I avoid them.

You will probably get caught out the first time or two - they charge you a cheap up front price but then add lots of little charges for all kinds of extras (luggage, checkin, that kind of thing). Once you know the system it works well.
