We do combine shipping on multiple items. - If all the items ordered ship USPS, eBay should combine the shipping automatically. 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. Just message us with questions or let us know what you want and we can send a shipping quote. We try to keep shipping costs as low as possible. Track Page Views With Auctiva's FREE Counter
