Dissapointed buyer, item malfunctions experience?


I sold a nice CD player that functioned perfectly up to the time I shipped. Buyer plugs it in and only one channel works. Box looks like no mishandling occured during shipping.
I spoke to the buyer, ( really nice guy). I also felt really bad about the item not functioning properly. I was going to refund all ship cost and payment.

He actually wanted to keep the unit so we agreed to have the unit fixed at my cost and I pay for ship to and from authorized repair shop.

This is the first time I have had to pay to have anything fixed that I have sold. I have been lucky and should be grateful because every transaction is a gamble.

I am curious as to what others have done in this situation and what possible pitfalls might occur during the repair process.

What has been your experience and is there actually a set of rules we should follow when this happens?
thanks

I not bright enough either to understand what SC53 is trying to say, except that what I get is that s/he is laying the foundation to get out of resolving the problem, if something is potentially damaged in transit. And the argument that will be used is this : I AM NOT A DEALER!
In conclusion: the Musical Fidelity CD Player that I bought was repaired @ Signal Path in Charlotte in less than 2 days, shipped to me almost immediately, and now functions perfectly. My cost, as a buyer was zero. Problem resolved. Both the buyer and the seller exchange positive feedbacks and shake hands over the phone. Case closed.
Well, the more complicated, delicate, or expensive the item, the more risk there is in: shipping it, selling it, or buying it used. I'm always wary of shipping CD or DVD players because they are so complex, & prone to failure anyway IME.

All of us here could just go buy all our gear brand new from dealers, but we want to get a bargain, so we buy stuff used, & save at least 50%, so then there's more risk involved. (Which is totally different from saying that A'gon sellers shouldn't totally try to accomodate the buyer, if there's a problem.)

There's always all kinds of risks to both buyers, & sellers, when buying used gear via the internet.....that's the nature of "getting a bargain".....
