Tikva, все нормально, они сначала блокируют, потом возвращают, потом опять снимают за каждую часть посылки при отправке
вот все многострадальные этапы оплаты
authorization: As soon as an order is placed, we authorize your card for the full order value. This authorization verifies that funds are available — it doesn't actually charge you or remove funds from your account. When one or more items are ready to ship, we again authorize your card for the cost of those items plus the shipping fee. Note: some financial institutions may hold funds along with authorization. If that happens, we ask them to reverse the hold so your funds are released until your items are ready to ship.
reverse: Some financial institutions hold funds along with authorization. If that happens, we ask them to reverse the hold so your funds are released until your items are ready to ship. Your card will only be charged when each item ships.
capture: Once your merchandise leaves our warehouse, we charge your credit card — this is called a capture. If your order ships in multiple packages, we charge each one as it ships, including the shipping fee with the first package and applicable tax item by item.
