Great idea, rj. If $1800 for social and food is average, it doesn't sound like a bad deal, if you compare to the fall meal plan of around $1750 (pretty close). Granted, not all meals are eaten at the frat, so there are more food costs, but it doesn't seem unreasonable. Plus you get all the social.
By the way, If you buy the meal plan, and end up pledging a frat, Food Services transfers the monies for the meal plan to the frat's dining fee. Any difference is given to the student in Flex Bucks. Say you invested in the meal plan at $1750, and the frat dining is $1200, you get $550 in Flex Bucks to use whenever. Food services requires the Frat to fill out some paperwork for the transfer of monies.
