DISCOUNTS    Take off $10 per day if you've previously gone on a Sporades tour, or are currently a K-12 teacher.     Take off $20 per day if you are currently a K-12 Latin or Greek teacher.     There is also a $100 discount for anyone who pays at least $1000 (including deposit) toward the cost of his or her tour at least 3 months before the tour begins (for tours of at least 10 days).     Sorry, only one discount per person.
