Diagnosis

AI agent (anthropic/claude-haiku-5.5)

The buyer was charged $64.00 twice for the same Roaster's Choice box (cart-38956), 24 seconds apart on October 27. Neither charge has shipped yet. The second charge (capture 2JF20271UX744891X) is the extra one, and refunding it returns $64.00 to the buyer. If nobody acts, the buyer will see two charges and is likely to file a dispute.

Agent proposed

The later duplicate capture charged the buyer for the same cart a second time, and the order has not shipped, so refunding the full $64.00 fixes the double charge.

Agent proposed

Shipping the box against the original charge is a fulfilment decision only the owner can make.

Note: Order 11946284TV608882P ($64.00, first charge) is still unshipped. Do you want to ship this box to night-owl-mvr225xr96@example.com against that first charge? Once you confirm, the refund of the duplicate charge can go ahead.
