Revolve認證？ - 海外購物

今天下午下好了訂單，剛剛收到Revolve寄來一封主旨是Your order is on hold
內容很長的一封信：

I'm very sorry, but before we can proceed with your latest orders we need to
verify that the cardholder authorized this purchase, with the following
security procedure. Please be assured that we will hold your items for you in
the meantime.

1) We place two tiny refunds to your card of random amounts less than $1 USD,
but we do not tell you the amounts. (We have already done this)
2) You call your credit card company or access your account online to
determine the refund amounts, and then correctly report the amounts back to
us.When you report the amount correctly, it proves to us that it is you using
your card, not somebody else (how else would you know the amounts?). We chose
this process because it seemed like the least inconvenient method to verify
your identity. Please note that some financial institutions take longer to
reflect refunds to your account than charges.
Typically, the refunds will post some time between 0 and 3 days after this
message, depending on your financial institution. After you have reported the
amounts, we will ship your order the same day.

We understand that you may not have encountered a procedure such as this
shopping online before, so we will attempt to explain below.

The reason for this procedure is to verify that it is you who are using your
card, and it is not someone who has simply stolen your card number.
Unfortunately, over the internet it is impossible to verify who is using the
credit card without additional security measures. It is also very easy to
steal a credit card number. Think about every time you hand your card to a
waiter at a restaurant, or a clerk at a retail store. Every time you do this,
it is an opportunity for your credit card number to be stolen. Obviously they
cannot shop at a retail store with only the number, but it is very easy for
them to shop online.

We appreciate your patience and understanding, and we sincerely apologize for
the inconvenience. If you have any questions regarding this procedure, please
let me know. We place the highest value on our service, and are terribly sorry
to inconvenience you with this request.

Thank you,

因為實在好長，我怕我理解錯誤，所以就po文想來詢問一下有經驗的版友

它內容的意思是說它要做身分驗證的動作，怕我不是信用卡的主人
所以退了不到美金一塊錢的金額到我帳戶，然後我要去確認金額再回報
等到我回報給它沒問題之後，它那邊才會幫我出貨這樣
然後這個退款的動作會在三天內完成，因為我剛剛用網路銀行查是還沒有退款進來啦...
不知道以上這些理解有錯誤嗎？在Revolve買東西的都會有這道手續嗎？

另外我爬文有看到第一次在Revolve購買會有折扣，我再下完訂單後有寫信去問
還沒有收到回覆，反而是收到這封信，也想順便請問一下首次購買的折扣是否還有呢？

希望有好心人能替我解答一下了，感謝！
