Don't want my money..?
Tried booking tickets for Universal Studios Japan via this website (you get automatically sent there from the USJ website for payment) but could not get payment to work. Tried different browsers, in both regular and private browsing, and tried both credit and debit cards, but couldn't get any payment to work. Went through one of their affiliate travel agent websites instead and payment worked fine.
