The cost of forwarding is not included in any subscription plan. Each mail item that you request to ship, will be charged separately. The price is determined by the mail item type, weight/ dimensions, carrier and shipping speed. Prices are set by your mail center. 

iPostal1 shows real-time shipping prices for any shipment you make by carrier (UPS, FedEx, USPS) and by level of service (overnight, 2-day, ground, etc.), and you choose the shipping that best meets your budget and timing needs. 

You can consolidate mail items into one package to save on shipping.
