I think I'm late to reply but if you need cash at the airport you don't need to check any of the above, there used to appear the "cash" choise formerly but not anymore.
cash has a disadvantage as the tax refund payer company takes %10 of the total tax refund as a comission when you request cash; if you choose the credit card option then it takes 6-8 weeks to issue the payment -but its safe, your money won't get lost- and you don't pay any comission. This comission thing matters when you are going to get a high amount of tax refund
Thank you for the reply. I'll keep in mind for the next time I go since I know I'll forget what I did when I did turn in my forms.
I did get cash though, since I wanted to pick up more souvenirs in duty free anyway. I don't mind the fee as it's almost like sales tax back home.
