Registration fees for the annual conference of the IPES are used to defray the costs of the meeting, including pre-ordered food and rented facilities. Although we recognize that cancelations may occur, we cannot adjust the costs of the meeting to accommodate last minute withdrawals. We will gladly refund your registration fee (by check) if you cancel and notify us at ipes@princeton.edu at least seven (7) days before the start of the conference. Cancelations received less than seven days before the start of the conference will will be noted but will not receive a refund of the registration fee.
