That's strange to me. I remember, and still think of, amazon as a marketplace. I bought used books and video games as my first purchases, waaaaay back when. You would have to sort out the prices and compare them to the listed 'condition' of the purchase, trying to figure out whether 'like new' condition was worth the $3 price jump over 'good' condition.
