- When buying an Interrail pass on interrail.eu, "Plus" (23 EUR extra) is automatically added on checkout. If you don't want that, you first have to notice it and then unselect it.
I'm not sure if it's allowed to add optional extras automatically but regardless of that: it is undesired. Please change that. - If you click on "Continue shopping" during checkout and then return to the checkout later, then "Plus" is added back again! This is even less desirable, since you should be able to trust that your order is not changed after you've saved it.
