How much does the ITIL exam cost?

Sorry to ask a Google type question but for some reason I cant find it on the ITIL site and Im getting conflicting prices on other sites! Havent even been able to find the darn exam objectives! Possibly my problem is me viewing the site on my phone o_0? Would appreciate it if you could provide this info, I have a laptop but no access to the net so all my googleing is done on my phone. Also I've heard you can sit the exam at home.. how?

Thanks
