Really sucks. I buy and sell quite a bit on ML, and on high-priced items I always include in the description that I will NOT sell to new buyers with no reputation unless they want to pay through MercadoPago. I had an almost-scare once with a digital photo frame. Not even that much of a high-ticket item, but the guy bought and then called my cell phone right away. He caught me off guard wanting me to give him the address to come pick it up right then. The call felt pushy and I sensed something wasn't right. Told him I'd email him the address. When I saw that he had just registered that day, I emailed him telling him that he would have to pay through MercadoPago if he wanted the frame. Never heard from him again. On a side note, one thing I've had terrible luck with is Subastas. The highest bidder follows through less than half the time and it totally screws up your reputation.
