no that would be the difference between a professional instruction, from someone with the a lot of credentials and boots on the ground time vs someone giving a basic three gun tutorial. The price ins't out there. Take a look at the professional training companies here in Canada and you'll see these courses are pretty close in pricing, and same on the US side with any of the well known training companies.
These courses are very physically and mentally demanding. This isn't just a fun outing at the range, this is serious training. It is really all dependent in what you are wanting out of the training you are taking. Class sizes are kept small, around 10 so there is really good instructor to student time.
Also take into account the cost of meals, travel, lodging, insurance etc that a professional company has to incur to do business. then there is the rental/user fees for the ranges being used. It all adds up. This is what these people do for a living...it's not a sideline or a weekend gig to make beer money.
