another note, after it's being stamp in Rome, u can choose to do cash refund or return back in credit card. Take the credit card options, it'll take longer time but if u take cash, they will only give you back in USD, in which the currency exchange rate from that Forex is super bad, you can lose up to 5% difference. Paris is the same case, I think they had limited to 200Euro maximum for cash refund in some system. So credit card refund will be the easiest and hassle free.
