Help with partial refund

[GaryBarlowsTaxReturn]

I sold a dress on eBay. It was BNWT and I'd only tried it on once. Thought it was immaculate condition. Buyer says there's a defect in the fabric and has asked for a partial refund. That's all fine & I'm not disputing her claim. Should I refund her through PayPal or ask her to open a case through the Resolution Centre first? The guidance from eBay about this doesn't tell me one way or the other.

Get her to open a not an eBay not as described Case, then there is an option for you to offer a partial refund to close the case.

The buyer can accept this and won't be able to take any further action.

Thank you Lottie.
