After a month, I personally wouldn't of offer a refund.
You're too nice, I personally wouldn't of offered a refund after a month.
I don't think I would have a choice. With eBay involved, they would just give it to him anyway. The money had even already gone from Paypal and I was owing them, so they bounced about the only annual subscription I have already.
Possibly I could have argued it was simply too late, but I think eBay would still side with the buyer.
I don't know the 'ins and outs' of eBay's T+Cs, but I'm very suprised to hear that eBay would side with the buyer a month after purchase...
I guess you've avoided the hassle/time of arguing about it anyway.
