Your customer night-owl-mw2e4m2b251@example.com was charged $64.00 twice for the same box (cart-29737), 20 seconds apart, on November 4.

Both orders are unshipped, so the refund and the choice of which order to fulfil both need the owner's decision.

The second capture is an exact duplicate of the first for the same cart, so refunding it returns the extra $64.00 to the customer and prevents a dispute.

Note: Hi, we noticed you were charged twice for the same box. We are refunding the duplicate $64.00 charge.
