For multiple product orders, we will try to send the download links in 1 e-mail, but you may receive multiple e-mails (1 per product). Products that are unavailable at the time of ordering will be sent as they become available, unless you inform us otherwise. You will only be charged for products contained in a given shipment, plus any applicable shipping charges. You will only be charged for shipping at the rate quoted to you on your purchase receipt. The entirety of this shipping charge will be applied to the first product(s) shipped on a multiple shipment order.
