Sold a used Canon HF-G10 on ebay to a guy in Texas. Unit sold for $1279. Sent out Tuesday morning via USPS priority with delivery confirmation and insurance. Got an email Wed night that the buyer did a Paypal chargeback, claiming the purchase was "not authorized". Yet Thursday they signed for and accepted the package. Spoke to Paypal about this, and I will be covered by the Seller protection plan, only because I provided proof that I sent the package. Had I not checked the "delivery confirmation" box in the Paypal shipping dialogue box, I would have been screwed. So, any time you sell anything on ebay, only: Ship to a verified address Do not ship to alternative addresses Ship with a carrier that provides full tracking and delivery information. This is key - I have shipped stuff before without checking the delivery confirmation box. This is frustrating as I truly feel this guy was hoping I'd send it without tracking, and then I'd be unable to prove I'd shipped it. Also frustrating that I cannot leave negative feedback for this guy, warning others, nor will I have access to the $1279 for at least 10 days while Paypal's fraud department wraps up their investigation. What is wrong with people?
