I had the same problem but then after 4 month

i got a mail from the buyer. She has moved and totaly forgotten to tell me the new adress. She say she doesnt need the cards anymore and i can keep them. She doesnt want a refund.
Another story:
Last month i sold a Buffy Basic Set. The Buyer didnt reply on my mails. After 20 days i got a mail from her. She will sent me the money as soon as she can (she was moved to).
I wait and yesterday i got the cash. Instead of 10€ for the Set and shipping she sent me 20€. I email her and told her that i will sent the 10€ back to her together with the cards.
Now i got a mail from her. I can keep the 10€ because i waited so long for the money.
