Waall Ektually (as they say in Africa) There's a lot more to it than that. One factor is how under or over populated a particular species is. If they have a big surplus then they may drop the trophy fee to get more animals shot. Then there is the drought factor, some species in some areas might not have sufficient water available so again they might lower the trophy fee, then there is the price & availability at game auction, (if they use game auctions) then there is the glamour factor and of course the time it takes for that particular species to reach maturity etc etc. Of course as you say the supply & demand factor is always there in every business. To say nothing about how the outfitter chooses to cut his cake. Some like to charge high camp fees and lower trophy fees and some the other way round.

The thing to be really cautious about is the place that offers a low camp fee and a low trophy fee...... There is no such thing as a free lunch.
