If you do not have an account with a freight carrier, shipping charges will be determined when your order is processed, and added to the total. Credit cards will be charged at the time of order-processing. If you want us to use your shipping carrier, please include your account number at the time of checkout. No order shall be binding on IPC unless and until accepted by IPC. IPC reserves the right to reject any order for any reason. Once submitted to IPC, an order may not be changed or cancelled by you unless such change or cancellation is expressly agreed to by an authorized representative of IPC. Any such change or cancellation may be conditioned upon you paying a change or cancellation charge intended to compensate IPC for costs incurred, including, but not limited to storage and shipping costs, costs of producing non-standard catalog items, costs incurred in purchasing materials, change or cancellation costs imposed on IPC by its suppliers, disposal costs incurred in disposing of Products in accordance with law, and any other cost resulting from a change or cancellation of an order placed by you. If IPC is unable for any reason to fill your entire order for Products, IPC may allocate its supply among any or all purchasers on such basis as IPC deems convenient and practical, without liability for any failure of performance which may result from such determination.
