Since your only contact in through e-mail and the such, they can essentially disappear on you, in only a number of a few seconds. Although, if you are indeed audacious enough to use ebay, you can often find a good bargain. So if the price looks right, trust your gut on whether or not it is a scam. Good luck on your purchase, if you do indeed buy. Ebay CAN be worth it. However, as I said, unless you're confident, watch your step, every step. Have fun on ebay!
