If its too good to be true ..
If it's only too good to be true by $1, someone is probably buying positive feedback for $1 per point. Fucking genius if you ask me. Spend a couple hundred bucks, get a decent feedback score, then scam some people on bigger items. You're not gonna get raped on this. You'll just be an accessory. Or maybe they're just trying to get their score up so they can attract more bids.
