And to expand on that more, HRC prefers people to buy the kit through vendors as this saves them the cost of having to do direct support. They can offer the vendor support and teh vendor becomes the front line for the customer. Providing support takes a lot of resources (man hours) which can affect cost since this was time that could be used elsewhere. It is usually cheaper to buy from somebody else other than HRC.
