Well, maybe you have some inside information. But I would seriously doubt quality control over money. If you buy a number of things from a 3rd party supplier of course there's going to be a few problems, but nothing money can't fix. You either get someone in their end or your end to add some additional quality control and that takes care of the quality. And you either have to pay a premium or you pay someone yourself that adds the cost that way. So if 90%+ are great, it's just a money problem making sure you only get those 90%. Either way sounds like a money problem and not a quality control problem.
