ok, about a month ago i sold a full suspension set up to a guy. i had no idea what condition they were in, so i sold them very cheep at 9 bucks a peice. they looked like they were in decent condition, but i made sure to tell him that i had never ridden on them and the condition was unknownd, and all i knew was that they looked like they were a decent set. well he wrote to me the other day saying that they are no good, and now he wants his money back. im not sure that a refund is nessesary due to the fact that i told him "they look good but i have never ridden on them" what do you think i should do?
