I purchased a used 23 inch ACD at the end of last month from a seller who had described it as being almost a year old. I paid $655. I checked the serial number and it was under warranty until March 28th and even called apple to verify this. When I purchased applecare, I found out that the monitor was three years old not one. I contacted the seller and asked for a partial refund due to the age (most monitors out of a year old were going anywhere between $450-$500. The seller declined. I opened a dispute on paypal and they agreed with me. I again asked the seller if they would consider a partial refund and again declined under the idea that the monitor is in great condition and age shouldn't be a factor. I'm resigned to shipping it back. Am I right in this matter or wrong? How would you have handled it?
