Is it legal for outfitters to charge more for outfitter allocated tags?

I was considering entering into the draw next year for an outfitter allocated hunt. When looking at the outfitter's website, I noticed that they charge more for the outfitter allocated tag versus a normal draw tag. I assume this is because a contract is needed prior to entering the draw, and they (the outfitter) can control who they sign that contract with. The whole idea of it seems fishy. Is this a legal practice?
