The flex points are usually at the ‘fast food’ places at the school and cost about the same as they would at an off campus place - smoothies about $5, sandwiches chips and drink about $7, Starbucks kind of drinks $5. Usually they can use flex point for the dining halls too, and they get charged a set $10-12 for a dinner. On a school term of 15 weeks, that’s only $10 per week average. You are right, $150 in flex dollars will not go far if he’s actually eating meals at them. If only using for coffees, sodas, bottles of water, he’ll be fine.
My daughter is living at the sorority house, and it charges about the same as the 12 meal/week plan at the dorm. The nice thing is that there is a snack room for off hours of meals with things like Mac and cheese, leftovers, granola bars, etc. to grab and go. I think it is a better deal than 12-15 meals at the dining hall just because she can get something at any time without needing to swipe for a full meal. Still a boat load of money for a few granola bars and some apples. I can feed my entire family for less than I pay for 1 term of meals at either of my kids’ schools.
