如题，九月下旬去了一趟欧洲
在机场退税刷玉山的JCB（负项，即所得）
回国后看到帐单，该笔退税欧元，先换成日币，再换成台币
汇率奇差无比
前一天用同一张卡刷另一笔（正项，即消费），就是欧元直接换台币
打电话去玉山，玉山说那是退税公司的问题，跟他们不相关
玉山说若是刷visa和master就会欧元直接换台币了
我去查了一下global blue的网页FAQ，是我的英文有问题吗？local currency不就是台币
有人也吃过这亏吗？

4.3 I want to choose credit card as preferable refund method. In which
currency will I receive my refund?
Global Blue supports these credit cards – Mastercard, Visa, Diners, Amex,
JCB, CUP.
If you want to receive your refund to Mastercard, Visa, and Diners, your
credit card will be credited in the currency, in which credit card is issued.
If you want to receive your refund to JCB and CUP, your credit card account
will be credited in your local currency.
In case of AMEX credit card, it will be credited in British Pounds (GBP).
AMEX will make conversion to the currency in which your credit card is issued.
If currency of your bank account differs from the currency in which Tax Free
Form is issued, the current “we sell” rates of a recognized European Retail
Bank plus 3 - 5% will be implied for the currency conversion.
