I recently sold a laptop that I feel was working fine, I had no problems with it but decided to upgrade. I listed for sale the old one for $350 and found a buyer willing to purchase it. We met and she checked it out and was happy to buy it and we struck a deal for $320. This was on the Sunday of last week. I was contacted Saturday night over the phone by a friend of hers telling me it is not working and hasn't worked since Tuesday and that I have two options - either fix it or refund her money, when he threatened to come to my house I hung up. I knew the computer worked well and so did she when she bought it. I said nothing of a warranty since I am only a private seller. The following night I received an email threatening to take me to small claims court if I don't return her money, also if she doesn't get her money she will make sure that everyone who checks out my electrical business online will know all about this sale. I sold this laptop in good faith and without misrepresentation and she also spent 20 minutes to 1/2 hour checking it out before giving me the money and leaving with the laptop. I agree it is unfortunate that electronics are unreliable and I do feel bad that it does not work if what she says is true but am I liable to return her money or even a portion?I know if she contacted me right away (Tuesday) and asked what we can do instead of almost a week later threatening me and my company (which has nothing to do with a private sale) I might think more kindly but I am upset at her tactics and attitude in this matter. What is my legal obligation to her?
