As someone who has posted a thread about bad buyers (well not bad buyers, but buyers with weird excuses), I'd love to see this one grow!

Had a buyer a few weeks ago, their purchase hadn't arrived, they waited two weeks, gave it plenty of time to arrive, but still no luck, so I gave them a refund promptly.
They thanked me numerous times for the refund. I didn't expect to hear back from them.
Then a week later their order arrived.
I received a PayPal payment with a lovely note, thanking me for refunding them, and letting me know it had arrived and that they had paid me once again.

The majority of buyers are wonderful. And there are a few extraordinary ones that stand out.
