Hi,
Last night I sold my Rokinon 8mm F3.5 lens through Kijiji for $160 CAD. At the time, the buyer saw a couple of little marks on the front glass which I couldn't see, but I don't have the best eyes either. Anyway, about 3 hours later, he contacted me asking to return the lens as he states the marks are dings. The lens works and I was finally able to figure out how to get sharp images with it.
I figure I have 3 options.
1) Tell him all sales are final and do not give a refund. He saw the marks, but bought the lens anyway. I really need the money to pay bills.
2) Buy back the lens and give him the refund.
3) Give him a $25 refund due to the defect. I still pay the bills and he gets a reduction in the price of the lens.
Last year I bought a camera and literally within 10 minutes of getting home, the sensor went on it. It's possible the guy was dumping the camera on me. It is also possible that it was just my luck that the sensor went belly up at that particular time. Either way, I didn't go back to him asking for a refund. I fell when buying or selling used, all sales are final.
So, I am really confused.
What would you do in this case? I will have to give him an answer by the end of the work day today.
