Yes, you can purchase a meal plan after meal plan service has begun. However, the cost for the meal plan remains the full amount for the first 7 days of meal service. After that time, the cost will be reduced by one day’s cost at the daily meal plan rate for either the 5-day or 7-day meal plans. Note: Because the meal plan cost stays the same for the first week, there is no cost advantage in waiting to get on the meal plan unless you have no choice due to funds availability.
