To add to Piglet's comment.
If it was that simple then we'd all be doing it. There seems to be a lot of grumbling on Le Mans sites about 'rip off agencies' so let me add a few points to consider.
To start off with, it costs in the region of €10000 to become an official ticket agent (for just one season!) so you've got to sell a shitload to make it worthwhile. You only get a 5% commission on sales too so do the maths.
In terms of renting a private space. It is of course possible but there is a minimum space you have (about 100 cars worth) and the price per sqm is about 4 times more than it would be if you simply bought 100 camping tickets. A hell of a lot more. Trust me! So, if TL's prices seem inflated then you know why.
From a personal point of view, for 2007 I am taking 15000sqm of space. I am putting up fencing, employing security marshalls, paying for a private toilet/shower block and adding a members bar and catering. So I am providing a lot more than a standard camping place and crucially, I am limiting the number of cars coming into that space so everyone gets loads more room than they would normally. And of course, that pitch is guaranteed no matter what day they show up and I can also put aside larger spaces for groups.
I have to run this event as a 'business' however, all I make out of it is enough to cover my costs. My end sale price is as low as it can possibly be without going into loss. Because I am a fan doing it for the fans but trying to offer a little more into the mix. It takes a
lot of hours to arrange and administer so in the end, it's not actually particularly profitable. The likes of Airtrack make profit when I can see how much it costs to run a similar operation to theirs and they are charging nearly 200% more than I will!
Notwithstanding, the use of my own chat forum in the run up to the event and the fact that everyone will be together in one spot means that I am lucky enough to develop an awesome team spirit and everyone feels like they know each other by the time they arrive. Everyone sharing plans, getting together for convoys and posting up pics of their cars before the off all stickered up. It's also perfect for newbies and those flying solo as they can easily meet people in the group who can show them the way and new friendships developed. We even have a boy/girl couple that met on my Le Mans tour in 2006 and are still together
So there's an example of by the fans for the fans. My absolute resolve is to provide value for money and at all times, to keep the cost of my camping operation as minimal as I can possibly make them. There are other events that I will do in due course where they might be more profitable but Le Mans is done for the love of it.
I hope this explains why tickets from independent operators have premiums.
