there are three stages to MOTO, card not present, transactions.

authorize, capture, settle.

authorize, check the card is good

capture, place a hold on the funds

settle, transfer the funds

merchants can do them as steps or do the first two at the same time

settle is a once daily end of day batch call to the credit card provider / bank

the first transaction failed at authorize, the next couple at capture, then the last at settle.

technically they all should have failed at authorize so likely something to do with amazon and how they process multiple transactions on the same card.

properly configured systems should ignore, treat as a mistake, multiple transactions for the same product / dollar amount within a 15 minute window.

but these were not duplicate transactions so would not have triggered that check

seems amazon may have skipped authorize for subsequent transactions and thats why they failed on capture or settle.
