A: Is this, by any chance, on a debit card, rather than a credit card? For some reason debit card holders see the reserve on their account as a charge, even though we do not have the money. Once we bill the order (at the time of shipping) the card is actually charged, and we receive that reserved money. The bank system would normally match the reserve total to the charge, and it would appear as a single transaction.
If the total changes, however, a new reserve will be placed for the new amount, and (if this is a debit card) you’ll see that as a separate transaction. The old reserve will never be charged, however, since on our end, your order is associated with only one reserve – the new one for the new amount. The old reserve will simply expire unused.
We only have one order for you, so can only get paid for the one charge.
You should be able to get more information from your bank if you have questions about that particular transaction. It should simply disappear from your record after the reserve period. We’re not sure how long that will be. For actual credit cards, the reserve can last as long as a month.
