A lot of our campers save up for the whole camp, some split it with their parents or have their parents cover a bulk of the cost and they cover the rest. What you need to do is research negotiation tactics on the internet, then sit down with your parents and test out your new found skills. Also, come to the table wth some leverage, like better grades, increasing your chores or something like that. That gives you a little bargaining power that if worked correctly, can go a long way!
Good luck and with a name like the "Thewizard", you should be able to work some magic!
