My daughter booked a car on this site and everything she clicked reversed when the confirmation cam through and at a lot mote money so be careful.
In fairness after phoning and some argument on the phone they gave a full refund to my daughter but tried to charge her 50 euros cancelation charge, but eventually dropped this as well.
I cant say whether the way they build their prices is fair and reasonable or not but my daughter is very on live savvy so I would say be careful thats all.
But they did do a refund so I cannot criticise this at all.
