When buying something used from a volume seller; items aren't always looked over as closely as a smaller sales company. That's why everything is rated by them to be either acceptable or good. I've been sent items that sometimes appear to have never been played, and sometimes items that live up to the acceptable rating (which is a playable but heavily used item). I've only once sent something back, and it wasn't hard to do. I've purchased many video games for assorted systems, dvds, and cds.
