It's great that a lot of people already know about this.
One of the points I want to make is that right now is as easy as it's ever going to be. I wouldn't go so far as to call it a price mistake, but IMNSHO the companies doing this are cutting corners and making decisions without gathering enough data. In the future, the companies will get better at gathering data sources and tiering their prices based on the results. They are operating half blind right now.
If they are willing to give away super preferred pricing to people who may only be basic preferred (because they can't tell the difference yet), why shouldn't you benefit?
