Thats why you learn the game, you lose a tiny bit of money, but you still make profit. I only accept Paypal, and when I send out packages I always pay the extra, I think $5 for signature confirmation. But yes there are a lot of scams out there. Luckily, out of the like 40-50 iPhones I sold, I only lost one(forgot the signature confirmation), guy said someone jacked the package from his doorstep.....
