I've been looking for a steering wheel for the Xbox One / PC for a few months now and found this bundle on Amazon after a bit of searching. The bundle had been going for $599 for the last few months, but just dropped down to the current $437 price yesterday (10/28/17). Unless I'm missing something, this seems like a really good price compared to buying all of these items separately. By my calculations, if you tried to purchase these items separately it would run you around $650-700. I've listed the Amazon/Best Buy prices for the individual items below for reference.
