Cost of purchase for a chimpanzee?

Depends on the breed.

I'm pretty sure that it is illegal to buy a baby chimpanzee unless you are an organization, like a zoo. Even if you are an organization like the zoo, you would only care for animals that are injured.

no it is illegal in Europe

they dont have a price tag.... Do you? also being a protected species you would go to jail if you were caught selling or buying one... good grief.

The U.S. paid 60 million francs ($11,250,000) plus cancellation of debts worth 18 million francs ($3,750,000), a total cost of 15 million dollars for the Louisiana territory.
