I'm currently interested in selling my laptop so that I can use the money to help purchase one that better satisfies my needs. It's still in very good condition (no mark or dents) and has only been used for a year. I have bought a 3-year warranty on it which I had purchased with the device from the local supply retail chain and I still possess the receipt for it, so I'm hoping I can recoup some of the cost back by offering both the product and the warranty. Would the new owner of the device be able to utilize the warranty if I give him the receipt? Could there be a security issue if my receipt no longer falls under my possession (I had paid for it with credit card and the receipt mentions the authorization number, which card I had used, and the last 4 digits of the card)?
