It is calculated by taking the heaviest item’s shipping cost plus the shipping cost for each additional item from the shipping and payments tab. -If there is a mix of USPS and UPS ORM-D Ground shipped items, then ALL the items will ship UPS ORM-D GROUND. Request an invoice after purchasing everything to receive a combined shipping invoice. UPS shipping is calculated and is based on weight and location. You can estimate it by using the shipping tab of the heaviest UPS ORM-D Ground item purchased to calculate its shipping cost. After that, it is usually about $0.50 per pound and it will never be more than what is stated for the additional shipping costs on the shipping tab.
