Our store's Terms of Service state that each individual order is considered a separate transaction, and as such, shipping fees are charged for each order. When you accepted the upsell offer, it triggered the creation of a new order with its associated shipping fee.
Shipping fee is not included in any discounted or upsell items that you purchase after your initial order as stated in our Terms Of Service under the section "Shipping & Handling Fees for Discounted Items". These fees are separate and must be paid in addition to the cost of the product because it is a separate cost that is typically charged based on the weight, size, and destination of the package. Including shipping and handling costs in the discounted offer may increase the overall price of the order.
