My understanding is that the Lotus 7 Club offer their members a package including crossing, hotels en route, entertainment and other features. The price includes an element of charity fund raising, as do some of their activities in LM (I saw a figure somewhere that they raised £24k last year...)
Because they block book tickets, they usually have some left over. How they price them I'm not sure, but Arnie Webb's adverts always say that proceeds go to charity. Why that should be in doubt, I'm not clear.
The full Lotus 7 package costs a lot, and I suspect that you'll find there is no subsidy from sales of spares. I think they fund raise in many other ways than just at Le Mans, and I'd be surprised if they don't have charity status which, I believe, brings with it legal obligations to keep accounts etc. They have a forum where I'm sure you can ask about this, if you want.

I'd sooner that the discussion on this topic stopped here, as false or misleading accusations could land this site in trouble.
I don't have moral dilemmas about what goes on here. I've been asked to try to make sure that "no profiteering" happens, that's all I'm trying to do, without offending people. I'd seek advice about anything I wasn't sure - after all, it isn't my site...
Isn't there something other than ticket prices to talk about?
