Diagnosis

AI agent (anthropic/claude-haiku-5.5)

Two refunds of $20.00 each were issued on the same $80.00 payment for the espresso sampler order, 3 seconds apart. This looks like a duplicate sent by a system retry, so $40.00 has gone back to the buyer in total, and $20.00 more than the one refund you may have intended. Nothing will be sent automatically; the extra $20.00 stays with the buyer until you decide what to do.

Whether the buyer should have received $20 or $40 is a business decision only the owner can make, and refunds cannot be run automatically.

Note: Refunds 3GU42375GX2618426 and 8H484643K51163030 each returned $20.00 from the $80.00 payment on order 8XN61138VD1171603 (espresso sampler), 3 seconds apart. Did you intend to refund $40.00 total, or only $20.00? PayPal cannot reverse a completed refund fr
